Answer 2

Hie! Here's your answer!

Answer:

a) 0.5

b) -0.23

Step-by-step explanation:

a) $\frac{-4}{5}$ x $\frac{3}{7}$ x $\frac{15}{16}$ x $\frac{-14}{9}$

∴ $\frac{-12}{35}$ x $\frac{-210}{144}$

⇒  $\frac{1}{2}$

⇒ 0.5

b) $\frac{3}{7} + \frac{(-6)}{11} +\frac{(-8)}{21} + \frac{5}{22}$

∴ (LCM=3234)

∴ $\frac{1386-1470-1386+735}{3234}$

∴ $\frac{-735}{3234}$

⇒ -0.22727

⇒ -0.23
