Question

Jimmy decided to make some granola bars to bring with him for the end of the year trip. The recipe he is using calls for 3/4 cup of granola for every 1/8 cup of peanut butter. Jimmy accidentally put a whole cup of granola in the mix.

Part A: what amount of peanut butter does jimmy need to put in the mix to have the same ratio of granola to peanut butter that the original recipe calls for?

Answer 1

Jimmy needs to put 1/6 a cup of peanut butter.

The way you would do the problem:

(3/4 )/ (1/8) =(1)/x

See how I set this up as a proportion.

Then you have 3/4x=1/8

x=1/6
