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

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

Answer 2

Answer:

7 1/2 cups of mix

Step-by-step explanation:

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

$\frac{1\frac{1}{2} }{7} =\frac{x}{35}$

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:

$\frac{3}{2} *\frac{5}{1} =\frac{15}{2} =7\frac{1}{2}$

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