Решите примеры1-3/8(17/121+48/121)-(60/121-27/121)х+7/15=14/1517/23-у=6/23

Решите задачу:

$1)1- \frac{3}{8} = \frac{8}{8} - \frac{3}{8} = \frac{5}{8} = \frac{5*125}{8*125} = \frac{625}{1000} =0.625 \\ \\ 2)( \frac{17}{121} + \frac{48}{121} )-( \frac{60}{121} - \frac{27}{121} )= \frac{65}{121} - \frac{33}{121} = \frac{32}{121} \\ \\ 3)x+ \frac{7}{15} = \frac{14}{15} \\ x= \frac{14}{15} - \frac{7}{15} \\ x= \frac{7}{15} \\ \\$

$4) \frac{17}{23} -y= \frac{6}{23} \\ y= \frac{17}{23} - \frac{6}{23} \\ y= \frac{11}{23}$
