Question

Show clearly how you would obtain an estimate for this calculation


`(607 * 4.97)/(0.214)`

Answer 1

Hi!

So we're going to round each number so that it's easier to estimate.

Round 607 to the nearest hundred.
600

Round 4.97 to the nearest 1.
5

Round 0.214 to the nearest tenth.
0.2

Now solve with the new equation.

`(600*5)/(0.2) = 15,000`

The answer is 15,000

If we hadn't estimated, the answer would be 14097.1495, which is very close to 15,000, so our answer is correct!

Hope this helps! :)
