(17/121+48/121)-(60/121-27/121)
х+7/15=14/15
17/23-у=6/23

Answer 1

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

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