Show clearly how you would obtain an estimate for this calculation

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.


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! :)
