Mel needs to measure 4 3/4 cups of flour. The only measuring cup he has measures 1/4 cup. How many 1/4 cups of flour should he use?

19

Step-by-step explanation:

Given:

measuring cup size = 1/4 cup

total amount to be measured,

= 4 3/4 cups (convert to improper fraction)

= 19/4 cups.

number of 1/4 cups

= total amount measured : 1/4 cup

= 19/4 : 1/4

= 19/4 x 4/1

= 19/4 x 4

= 19 (1/4-cups) used
