Question

13. Is 100 a reasonable estimate for
915.25 +88.22? Explain.

Answer 1

Answer: Not at all

Explanation:

1000 would be a reasonable estimate not 100

915.25+88.22=1003.47 which is not close to 100

Also, the first number is much more than 100

so how can it be reasonable.

Answer 2

No, it should be 1010

Explanation:

915.25 rounds to 920

88.22 rounds to 90

920+90=1010

Answer = 1010
