Question

Show me an example of multiplying decimals

Answer 1

Simple example of multiplying decimals

1.1 * 2.5 = 2.75

or 

2.3 * 3.2 = 7.36

Answer 2

4.50 * 30

What I do is ignore the decimal until the very end of the problem.
450 * 30 = 13500

Since the decimal has two numbers behind it, you start from 13500 to 135.00 
Which obviously can be written as 135.
