Answer 2

Answer Step-by-step explanation:

a) $\frac{4}{5}$ - $\frac{1}{2}$ = $\frac{4 X 2 - 5 X 1}{5X2}$         (cross multiply)

           = $\frac{8-5}{10}$

           = $\frac{3}{10}$

⇒         = 0.3

b)$\frac{-3}{5}$ - $\frac{2}{7}$ =  $\frac{-21-10}{35}$

           = $\frac{-31}{10}$

⇒        = -3.1

c) -2 -$\frac{4}{9}$ = $\frac{-18-4}{9}$  

           = $\frac{-22}{9}$

 ⇒       = -2.4

d) $\frac{-3}{8}$ - ($\frac{-2}{5}$) =$\frac{-15+16}{40}$  

                 = $\frac{1}{40}$

 ⇒             = 0.025

e)$\frac{-5}{14}$ - ( $\frac{-1}{7}$) = $\frac{-35+14}{98}$

                 = $\frac{-21}{98}$

⇒               = -0.214

f)$\frac{12}{15}$ - $\frac{1}{5}$ = $\frac{60-15}{75}$

          = $\frac{45}{75}$

⇒       = 0.6
