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
