Question

Brian baked 84 pizzas. If each pizza tray held 9 pizzas, how many trays did Brian used?

• A. $9$
• B. $8$
• C. $10$

Answer 1

The correct option is C $10$

Total number of pizzas $=84$
Number of pizza each tray can hold $=9$
Number of trays Brian used $=\frac{\text{total number of pizzas}}{\text{number of pizza each tray can hold}}$

$=84÷9$

Quotient = 9
Remainder = 3
After 9 trays are occupied, There are still 3 pizzas remaining We need one more tray for the remaining pizzas.
Hence, We Round up.
Therefore, Total number of trays used $=9+1=10$
