Answer 2

Questions 1–3 are marked correctly. (See your other posting of these questions.)

4.

$\left(\dfrac{5}{3}\right)\left(\dfrac{3}{5}\right)=\dfrac{(5)(3)}{(3)(5)}=\dfrac{(3)(5)}{(3)(5)}\\\\=1\qquad\text{numerator = denominator}$

5.

$\dfrac{2}{5}(-7)\dfrac{5}{2}=\dfrac{(2)(5)}{(2)(5)}(-7)\\\\=-7$
