Question

First use front end rounding to round each number and estimate the answer. Then find

the exact answer.
6.48
X 1.8

Answer 1

Explanation:

The answer should be somewhere near 6* 2 = 12 which is the first answer. Do not put an exact answer when you are asked for an estimate.

The exact answer is 6.48 * 1.8 = 11.664 which makes 12 look like a pretty good estimate.
