Lesson Steps:

The easy method to do this is to first multiply both numbers ignoring the decimal point and then, add the decimal point in the end.

708×30
=708×3×10
=2124×10
=21240

In the original question, 7.08 had a decimal point two digits from the right side, and 30 had none.
So, put a decimal point two digits from the right side of the obtained answer, i.e., 21240 becomes 212.40
