Question

Choose the best estimate for the multiplication problem below.

82.17
7.32
X
A. 560
B. 860
C. 420

Answer 1

Hey there!

We see that the first factor is 82.17, which is about 80. Then, we have 7.32, which is about 7.

80 times 7 is just doing 8 times 7 but putting a zero on the end!

So, 80 times 7 is 560, so our best estimate is A.560

Have a wonderful day!
