On her way to work, Lily purchases a coffee from Starbucks. She adds 1/2 oz of half-and-half, a mixture that is half cream and half milk, to her cup. Because of her high cholesterol, she only allows herself 2/3 oz of cream per day. What fraction of her daily allowance of cream does this drink contain?

Since 1/2 oz of the ha;f-and-half is 1/2 cream.....then the amount of cream contained is (1/2)(1/2) = 1/4 oz cream

 

So

 

Amt of cream in half-and-half                  (1/4)

_________________________   =       ______ =   (1/4) (3/2) =   3/8

Total allownce of cream per day              (2/3)

 

 

3/8 of the daily allowance
