– [Voiceover] Let’s figure out what 6.3 divided by 0.25 is. And when I look at something like this, the first thing that

I think about is well, is there a way that I can rewrite this? Instead of dividing it by 25 hundredths, instead of dividing it by 0.25, I could divide it by a

whole number, maybe 25. And so how do I turn

25 hundredths into 25? Well, if I multiply it by, if I multiply it by 10 once, then. the decimal’s one spot to the right. And if I multiply it by 10 twice, then I’m gonna move

two spots to the right. And 25 hundredths is going to become 25. I multiplied by 10 twice,

which is the same thing as multiplying by a hundred. Now of course, I can’t only do it to 0.25, that would change the value

of this entire expression. I also have to do it to 6.3. If I move the decimal to

the right twice over here, to get a whole number, I gotta move the decimal twice to the right over here. So let’s see, if I move

it to the right once, I get 63, so that’s one

multiplication by 10. And now I wanna move

it to the right again, and you might say, “Wait,

wait, there doesn’t look like “there’s any other digits here “that I can move to the right of.” And we just have to remind ourselves, that 6.3, well that’s going

to be the same thing as 6.30, or we could actually as many zeroes as we want to the end of this, and not change the value, it’s still 6.3. Six and three tenths is the same thing as six and 30 hundredths. So now, I can move the decimal

one more spot to the right. And, so I’m multiplying by 10 again. And it becomes 630. So 6.3 divided by 0.25 is the same thing as 630 divided by 25. And let me do that again, because this is really, the

tricky part, or the artful part, when you’re dividing decimals. If I were to write, 0.25, being divided into, being divided into, 6.3. Six, let me do it. Six, 6.3. Now, what I care about is moving

this decimal to the right, far enough so that this

becomes a whole number. I don’t have to move it any further, just far enough so that

this becomes a whole number. And then I have to move this, the same number of times to the right. But the goal is to make

this a whole number, not to make the 6.3 a whole number, although that is going to

happen for this particular case. So if I move it two spaces to the right, so, one, two. 0.25 becomes 25, and then 6.3 becomes, move it one space, two

spaces to the right, it becomes 630. And so let me, let me clarify that, let me just clear all of this

stuff away out of the way, to just make that clear what I just did. So we don’t have to deal with all of this messiness when we’re actually doing our long division now. And so this one over here, let me erase all of this business. And we are ready to do some, we’re ready to do some,

some long division, alright. So now this is just straightforward, dividing a two digit number

into a three digit number. And so we could say, well, 25 goes into six zero times, so let’s keep going. 25 goes into 63, let’s see, two times 25 is 50, three times 25 is 75, so that’s too much, so we wanna go two times. Two times 25 is going to be 50, and we can subtract. Or, if you didn’t know two

times 25 is going to 50, you could have said two times five is 10, carry the one or regroup the one. Two times two is four, plus one is five. So we got 50. And now we subtract, and we get three minus zero is three, six minus five is one. And now we bring down the next digit. We can bring down this zero. And we could say, 25, and let me scratch this out, so I

don’t confuse myself later. 25 goes into 130 how many times? Let’s see, 25 times four is 100, 25 times five is 125, 25 times six would be

150, so that’s too big. So I’m gonna go five times. So five times, And I write, it’s very important to keep track of my places right here, I brought down the zero to make the 13 into 130, so I say 25 goes into 130 five times, I write it above the zero, I write it right above

the zero right over there. And then five times 25, five times five, we already know what it is, but I’ll just figure it out. Five times five is 25, regroup the two, five times two is 10, plus two is 12. And now we can, now we can subtract. And you might know

offhand, well (mumbles), 130 minus 125 is going to be five, or if you like, you could

do a little regrouping, can make this, you could

take a 10 from there, and then put the 10 in the ones place, and this becomes 10,

10 minus five is five. Now, we aren’t done yet. We wanna divide this completely, so we can bring down another zero. We can bring down another zero, and I’m picking an appropriate color, to, for the next, so I’ll use, well I already used the green once, we’ll use yellow. So once again, I can

bring down another zero, but I have to be very careful here, I can’t just, I can’t just throw a zero right over there. That’s gonna turn 630 into 6300. I have to be very particular,

say no, look, look. This next zero I’m gonna put, that’s gonna be after the decimal. Now 630 is the same thing as 630.0, and if I’m gonna add a decimal there, I wanna throw the decimal right above it. Need to be very careful with that. But now we’re ready to start

bringing down the zero. So let’s bring down this zero. And we have 50, how many times does 25 go into 50? Let me scratch this out, so we don’t confuse ourselves later. 25 goes two times into 50, two times 25 is in fact 50, is in fact 50. And so now we can subtract. And we now have a remainder of zero, and there’s nothing left to

bring down other than zeros, and we have a remainder of zero, so we are done dividing completely. You take 630, divided by 25, it’s 25.2. Or if you look at our original problem, if you look at our original problem, which was 6.30 divided by 0.25, that also is 25.2. So this is also going to be 25.2. Let me rewrite it, let me rewrite it. So our original problem was 6.3 divided by 0.25, which we just figured out, what we just figured out is 25.2. And we’re done.

Hey thanks really helped this was really simple

Great explanation

thanks, this helped my little sister a lot

Life.LoLLolh Pink Sheep

this helped me so much

🙂

Thank you! this really helped

Helped a lot, thx

thanks for teaching me better than my teacher did

This is really fifth grade? I feel like I don’t listen in class now holy crap 😂😂😂

thank you SO MUCH IT HELPED GOT A+

he is the best teacher ever

Can you do that sum with short division or does it have to be long division?

OMG this really helped! Also, it seems like you know every single math problem in the world.

I feel dumb cause im trying to understand this kind of math in 6th grade!2018

Ayyyy bro! I appreciate it

This was so helpful to me

thanks

this is helping alot im in 5th grade and now i get a' and b'

5th grade got a A+ on tets with out this but my teacher told me to watch

stop pickin on 5th grade because im in 5th grade

this was very helpful

😂😂I RATHER LISTEN TO U TEACHING US THAN LISTENING TO MY TEACHER😂😂😂👍👍 U EXPLAIN BETTER… PROBABLY I DONT LISTEN TO MY TEACHER😂😂 BUT THANKS💗💗💗

Am 10 and have a 5th grade test am 10 why to young like if u agree #bad grammar

Thank u,next next by next video

srry dont get it😕

i got 0.039

Arent you supposed to move the decimal in the answer 2x over

Who watching 2019

What aboud 0.7/ 23.1

Thank yo7,,,,,,,,,,

This is the hardest thing. I’m in fifth grade and even my high school BROTHER can’t even help me, I have problems like 3.78 divided by 8.988. The two hard things I can’t figure out is having no remainder and dividing number decimals that doesn’t even have the same place value. .78 and .988

.78 has hundredths and .988 has thousandths, it doesn’t go evenly together.

ya

Didn’t help at all

I don't get this all and I have a math test on this tomorrow and I'm panicking I've searched up about more of 10 of these videos and i still don't get it I also have work from other classes oh god please help me 🙁

Thanks you for this video.

My brain hurts after this

wow so helpful totally passing my quiz ;0

i agree royal ocean how dose he write like that

6.3/0.25=25.2

thank u for making dis vid u are getting smarter ever second an u help me pass my test/quiz

OMG god bless you I have test tomorrow

OR you can do 63 divided by 2 and divide that BY 4(to get it to .25) and put the decimal point in your done

I have a TCAP TEST tomorrow it's really hard but you made this very easy for me Than my Teacher 😁😀

who else is here for th state test

I hope when I try this in class, my teacher will accept it 😬

This does help a little

i have nwea tomorrow i am in third grade

Literally need to relearn 5th grade math for my MCAT… I'm a Junior in college lol

Well… This is 4th grade at Korea… But sal, you are great.

Thank u so much

My parents actually forced me to do this and I thought I would get everything wrong and it would be a bit hard, but thus person helped me so much. The colors actually make everything easier. Thanks Khan Academy!
