Answer:
1. 3/10 is equal to .3 or 30%
2. 7/10 is equal to .7 or 70%
3. The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = (30 +20) you can distribute the value outside of the parentheses to the values inside.
