Question

How do you estimate `297 times 32` by rounding?

Answer 1

It's approximately 9000.

Explanation:

You can see that 297 is significantly close to 300, and 32 is significantly close to 30. This is to say that if you round each value to the nearest tenth, you'd get 300 and 30.

`297~~300` and `32~~30`

`therefore 297 * 32 ~~ 9000` because `300 * 30 = 9000`
