А) $\frac{1}{2}$ * (x+ $\frac{4}{5}$ )-( $\frac{1}{5}$ -x) =

= $\frac{x}{2}$ + $\frac{2}{5}$ - $\frac{1}{5}$ + x= 1.5x+0.2

Б) $- \frac{2}{3}$ * ( $\frac{6}{7}$ -y) + $\frac{2}{7}$ +y

= - $\frac{4}{7}$ + $\frac{2y}{3}$ + $\frac{2}{7}$ +y=

= $- \frac{2}{7}$ + $1 \frac{2}{3}$ y

В)-(y+ $\frac{1}8}$ ) + $\frac{3}{4}$ * (2+y) =-y - $\frac{1}{8}$ +1.5 + $\frac{3y}{4}$ = $- \frac{y}{4}$ +

+ $1 \frac{5}{8}$

Г) $\frac{1}{9}$ * ( $\frac{3}{5}$ - x) - (x- $\frac{1}{15}$ ) = $\frac{1}{15}$ - $\frac{1}{9} x$ -x + $\frac{1}{15}$ =

= $\frac{2}{15}$ - $1\frac{1}{9} x$
