Question

A cook has 2 2/3 cups of flour. A recipe calls for 2 3/4 cups of flour. Does the cook have enough flour? If not, how much more flour is needed

Answer 1

No. the cook does not have enough flour.

2 3/4= 11/4

2 2/3= 8/3

11/4-8/3= 33/12-32/12= 1/12 more flour.

Answer 2

What he has: 2 2/3 = 8/3 cups
What recipe needs = 2 3/4 = 11/4 cups

Amount missing = 11/4 - 8/3 = 33/12 - 32/12 = 1/12
He needs 1/12 cups more, or 4 teaspoonfuls, or 20 mL.
