Question

A recipe calls for 2 eggs to make 10 pancakes.How many eggs will you need to make 35 pancakes?

Answer 1

you would need 7 eggs

Answer 2

Set up the proportion. Then cross multiply and isolate the variable to solve.

`(2(eggs))/(10 (pancakes)) = (x)/(35 (pancakes))`

2(35) = 10(x)

70 = 10x

`(70)/(10) = (10x)/(10)`

7 = x

Answer: 7 eggs
