Answer 1

Answer:

(a) -60  and (b) -1/2

Step-by-step explanation:

here, In first case (a)

$\frac{3}{\frac{1}{2}}$/$\frac{-3}{5} +\frac{1}{2}$

= 6/$\frac{-1}{10}$

= -60

now, In another case (b)

$(\frac{-1}{4}-(\frac{-1}{6}))$/$(\frac{1}{3} + (\frac{-1}{2}))$

= $\frac{-1}{12}$/$\frac{1}{6}$

= $\frac{-1}{2}$

hope it will help you.
