Question

Gabriela drank 3/4 of her glass of milk and Jenny drank 6/8 of her glass of milk. If the glasses were the same size, did they drink the same amount? Use cross multiplication to prove your answer.

Answer 1

they drank the same amount, they just used different measurements to prove it.

Explanation:

6/8 divided by 2/2 equals 3/4

And 3/4 x 2/2 equals 6/8

Hope this helps :)

Answer 2

They drank the same amount of milk

Explanation:

Equivalent Fractions

Given the fractions

`(a)/(b), \ (c)/(d)`

They are equivalent if:

`(a)/(b)= (c)/(d)`

Using cross-multiplication:

ad = bc

We are given Gabriela drank 3/4 of her glass of milk and Jenny drank 6/8 of hers. If both glasses were the same size, we can find if they drank the same amount of milk by proving:

`(3)/(4)= (6)/(8)`

Using cross-multiplication:

3*8 = 4*6

Since 24 = 24 is true, we can say they drank the same amount of milk
