Answer:
1. 100
2. 100
3. 5600
Explanation:
The steps are breaking down both of the numbers to simpler terms to more easily multiply them.
7 times 800 can be broken down to
7 times 8 times 100 (since 8 times 100 equals 800)
then it multiplies 7 and 8 only
so
56 times 100
then it multiplies it all
56 times 100
5600
