Adam made potato salad for the picnic. He made 20 cups of salad. At the end of the picnic, there were 3 3/4 cups of salad left. How many cups of salad were eaten at the picnic?
Let x be number of
cups of salad eaten
20 - x = 3 3/4
- x = 3 3/4 - 20 ; 3/4 = 0.75
- x = 3.75 - 20 -1 (- x = -16.25)
x = 16.25 ; 0.25 = 1/4 ; x = 16 1/4 cups
