Question

Kim multiplied 8×0.952 and got 76.16. How can you estimate to show that Kim's answer is incorrect?

Answer 1

You multiply 8 by 1 because if you round up it will be an estimate
8 x 1 = 8

Answer 2

Answer with Step-by-step explanation:

Kim multiplied 8×0.952 and got 76.16.

As we can see 0.952 is a number near to 1

i.e. 0.952 ≈ 1

So, 8×0.952 ≈ 8×1

i.e. 8×0.952 ≈ 8

There is a huge difference between 8 and 76.16

Hence, Kim's answer is incorrect
