Question

Jacey has 40 pizzas to sell in the concession stand at a basketball game . Each pizza has been cut into 8 slices of equivalent size. In the first hour, Jacey sold 16 3/8 pizzas . In the second hour , she sold 18 3/4 pizzas . How many pizzas does Jacey have left to sell?

Answer 1

40 pies * 8 slices = 320 total slices.

In 1 hour = 16 3/8 slices sold.
In 2nd hour = 18 3/4 slices

16 3/8 + 18 3/4

Find Lowest Common Denominator:

3/4 -> 4/8

16 3/8 + 18 4/8 = 32 7/8

320(total slices) -32 7/8(slices Janey sold)= 188 1/8 slices (leftover slices)

Answer: 188 1/8 slices left to sell.
