Question

In a survey four out of five people preferred creamy peanut butter over chunky peanut butter. There are at 120 people shopping at the grocery store. Use the survey to predict how many people in the store would prefer creamy peanut butter.

Answer 1

96 people out 120 people. 
Since we know that 4 out of 5 people preferred the creamy peanut butter over the chunky peanut butter, all you have to do is use this info to solve. 

4/5 = ?/120
120/5 = 24
24 x 4 = 96
The answer is 96. <span />
