Answer 1

The Solution.

1.

$(-14)+81=81+(-14)\text{ }\Rightarrow Commutative\text{ property of addition}$

2.

$\frac{1}{3}(24+15)=\frac{1}{3}.24+\frac{1}{3}.15\text{ }\Rightarrow\text{ Distributive property}$

3.

$\frac{13}{17}\times\frac{17}{13}=1\text{ }\Rightarrow Multiplicative\text{ inverse}$

4.

$-72+0=-72\text{ }\Rightarrow\text{ }Additive\text{ Identity}$
