Question

Round to the nearest ten and thousand, then estimate the product. 66 x 2,954 = ___ 120,000 140,000 180,000 210,000

Answer 1

Answer: 210,000

Step-by-step explanation

66 is close to 70 when rounding to the nearest ten.

2954 is close to 3000 when rounding to the nearest thousand.

70 x 3000 = 210,000

This is because 7 x 3 = 21. Then we add on 4 zeros. The first zero comes from "70". The other three zeros come from "3000". That's why we have 1+3 = 4 zeros in total.
