First Problem:
1/2 * -2 2/5 = 1/2 * -12/5 = -12/10
Simplify -12/10 into -6/5
Step-by-step explanation:
Unit form is putting all numbers in place according to its place value.
The proble states 7 hundred which means that 7 is in the one hundreds place.
7 * 100 = 700

There is a pattern of 8 after each number (b)
For 8, it's 6.2 . For 9, it's 7.0 (or 7)
