A carton contains milk that is 2% fat, an amount that is 25% less fat than the amount contained in a carton of whole milk. What is the percentage of fat in whole milk?   

 

Saying "25% less" is the same as saying "75% of".  

 

2% = 0.02  and  75% = 0.75  

 

Let x stand for the percentage of fat in the whole milk. 

 

(0.75)(x)  =  0.02  

 

           x  =  (0.02) / (0.75)  =  0.02667  

 

           So, the amount of fat in the whole milk is 2.667%  

 

Check Answer  

 

(0.02667) • (0.25) = 0.00667  

 

0.02667 – 0.00667 = 0.02
