Question

one recipe for pancakes says to use 1 1/2 cups of mix to make 7 pancakes. How much mix is needed to make 35 pancakes

Answer 1

7 1/2 cups of mix

Explanation:

This looks like a question involving proportions, so I'm going to set up some proportions to help us find the correct answer:

`(1(1)/(2) )/(7) =(x)/(35)`

What I immediately notice is that I can multiply the 7 on the denominator of the first proportion by 5 to get to the denominator of the second proportion, which is 35.

So, I can multiply 1 1/2 (or 3/2) by 5 to find the value of x:

`(3)/(2) *(5)/(1) =(15)/(2) =7(1)/(2)`

So, the answer is 7 1/2 cups of mix. Hopefully that's helpful! :)

Answer 2

7 1/2

7 pancakes = 1.5 cups
35/7= 5
1.5 x 5 = 7.5
