The first thing we are going to do in this case is to find the following product:
\(7 * 20\)
We then have to multiply:
\(7 * 20 = 140\)
Then, we have the following product:
\(7 * 2000\)
Rewriting the product we have:
\(7 * 20 * 100\)
Then, using commutative property we have:
\((7 * 20) * 100\)
Substituting values:
\((140) * 100\)
When you multiply by 100, you only have to add two zeros to the right.
We have then:
\((140) * 100 = 14000\)
Answer:
\(7 * 20 = 140
(140) * 100 = 14000\)
