So I’ve got a whole

pizza here, and let’s say that I were to cut it

into two equal pieces. Let me cut it right over

here into 2 equal pieces. And let’s say that I ate

one of those 2 equal pieces. So let’s say I ate all

of this right over here. What fraction of the

pizza have I eaten? Well, I took the

whole and I divide it into two equal pieces, and

then I ate one of those pieces. So I ate 1/2 of the pizza. Now, let’s imagine that instead

of cutting that pizza into only 2 equal pieces,

let’s imagine instead that decide to cut it

into 4 equal pieces. So let’s draw that. So 4 equal pieces. So I could cut once

this way and then I could cut it once this way. And so here I have

4 equal pieces. But let’s say that I want to

eat the same amount of pizza. How many of these 4 equal

pieces would I have to eat. I encourage you to pause the

video and think about that. Well, I would eat this piece. You could imagine me eating

this piece and this piece right over here. I’ve eaten the same

amount of the pizza. Each of these pieces you could

imagine got cut into 2 pieces when I cut the whole

pizza this way. And so now I have to

eat 2 slices of the 4, as opposed to 1 slice of the 2. So I just ate 2 out

of the 4 slices. I’m using different

numbers here. Here I’m using a

1 in the numerator and 2 in the denominator. Here, I’m using a

2 in the numerator and a 4 in the denominator. These two fractions

represent the same quantity. I ate the same amount of pizza. If I eat 2/4 of a pizza, if I

eat 2 out of 4 equal pieces, that’s the same

fraction of the pizza as if I eat 1 out

of 2 equal pieces. So we would say that

these two things are equivalent fractions. Now let’s do another

one like this. Instead of just dividing

it into 4 equal pieces, let’s divide it

into 8 equal pieces. So now we could

cut once like this. So now we have 2 equal pieces. Cut once like this. Now we have 4 equal pieces. And then divide each of

those 4 pieces into 2 pieces. So I’ll cut those

in– So let’s see. I want to make

them equal pieces. Those don’t look as

equal as I would like. So that looks more equal, and

that looks reasonably equal. So now how many equal

pieces do I have? I have 8 equal pieces. But let’s say I wanted to eat

the same fraction of the pizza. So I could eat all of these

pieces right over here. Well, how many of those 8

equal pieces have I eaten? Well, I’ve eaten 1, 2, 3,

4 of those 8 equal pieces. And so once again, this

fraction, 4 of 8, or 4/8, is equivalent to 2/4,

which is equivalent to 1/2. And you might see a little

bit of a pattern here. Going from this scenario

to this scenario, I got twice as

many equal slices. Because I had twice

as many equal slices, I needed to eat two times

the number of slices. So I multiply the

denominator by 2, and I multiply the

numerator by 2. If I multiply the numerator

and the denominator by the same number,

then I’m not changing what that fraction represents. And you see that over here. Going from 4 slices to 8

slices, I cut every slice, I turned every slice

into 2 more slices, so I had twice as many slices. And then if I want to

eat the same amount, I have to eat twice

as many pieces. So all of these, 1/2, 2/4, four

4/8, and I could keep going. I could do 8/16. I could do 16/32. All of these would be

equivalent fractions.

stupid

this help me alot

lame

Very clearly explained

This helps me .thank you so much

thanks so much you made math so easy 😇🐩😇😁😂😀

very helpful

helps me a lot

it helped me understand it but didn't solve my homework

i already know this i am watching this for fun

easy!

I'm getting hungry

stipud

u guys know this song blank space

I have a retest coming up and this helped me sooooooooooooooooooooo much!

clear

pizza

Me too

I love math

wowo she is very easy!

hmmmmm? I dont understand. 🙁

mmmm piiiizzzzzzzzaaaaaaaaa

and this didnt help me at all because i am in 5th grade and i am trying to do it with letters so you dont help at all

Very clear information thank you 😊

Good

Nice

Do you have real pizza for me?，💋🍕🍕🌶🍗🍖🍤🍳🍔🍟🌭🍝🌮🌯🍜🍲🍣🍱🍛🍙🍽

It helps me a lot of things! Thank you! 🍕🤓

Pizza

I didn’t understand my math lesson so uh here I am;(

Helps me understand but maybe won't help me fix my test

Who came here to help with there work 😞😞😞

what if the pizzas were different sizes?

This is 3rd grade work. Going into fourth grade and I’m one half and a quarter sure.

Why don’t you just say whatever the fraction is, multiply by 2. Oh crap you did I’m being an artard lol.

helped me who ever is reading this a a good day!

This helped me very much and I felt very good

Thank you i missed school today
