Question

Walnuts, peanuts, and chocolate chips are mixed composed in a ratio of 7:2:5. What is the weight of the mixture if 2.5 lbs of chocolate chips were used for making it?

Answer 1

2.5 pounds is 5 parts of the mixture.

0.5 pounds is 1 part of the mixture.

14 parts (7 = 2 + 5) make up the entire mixture.

14(0.5) = 7

 

The whole mixture weighs 7 pounds.

 

Check:

7(0.5) = 3.5

2(0.5) = 1

5(0.5) = 2.5
