How can 1.5m multiply 8m?

Trick 1: Use calculater. Ok ok. Just kidding.

Trick 2:

1. Multiply 8 by 15. Because we get fifteen if we move the decimal one place right.

2. Then you will get 8×15 = 105. Ok?

3. Then you know that we can write 105 as 105.0 or 105.00 etc.

4. Just move the decimal one place left. One place left because we moves it one place right in the first step. So, it becomes, 10.5
