Use rounding or compatible numbers to estimate each product or quotient. 5x2 3/5 about 10 about 10 3/5 about 12 about 15 2. use rounding or compatible numbers to estimate each product or quotient 25 7/8 divided by 2 8/9 about 9 about 10 about 11 about 12 3. mr. garcia's class at 3 2/3 pizzas, mrs rizzoli's class ate 4 1/8 pizzas, and mrs. tindal's class ate 3 1/4 pizzas. use benchmarks to estimate the total number of pizzas eaten by all three classes. about 9 about 10 about 11 about 12

Part 1

Using rounding or compatible numbers, we estimate the product


to


Therefore, the estimate of the product , using rounding and compatible numbers is about 15.

Part 2

Using rounding or compatible numbers, we estimate the quotient


to


Therefore, the estimate of the quotient , using rounding and compatible numbers is about 9.

Part 3

Given that Mr. Garcia's class ate pizzas, Mrs Rizzoli's class ate pizzas, and Mrs. Tindal's class ate pizzas.

Using benchmarks, we estimate the total number of pizzas eaten by all three classes as follows: , and

Thus, the total number of pizzas eaten by all three classes is given by



Therefore, the total number of pizzas eaten by all three classes is about 11.
