Question

Решите уравнения с дробями: 1)х+5/14=5/6 2)17 целых 3/8-у=9 целых 5/12+2 целых 1/6

Answer 1

$1) x+ frac{5}{14} = frac{5}{6}$
$x= frac{5}{6} - frac{5}{14}$
$x= frac{35}{42} - frac{15}{42}$
$x= frac{20}{42} = frac{10}{21}$

$2)17 frac{3}{8} -y=9 frac{5}{12} +2 frac{1}{6}$
$y=17 frac{3}{8}-(9 frac{5}{12}+2 frac{2}{12} )$
$y=17 frac{3}{8} -11 frac{7}{12}$
$y=17 frac{9}{24} -11 frac{14}{24}$
$y=5 frac{19}{24}$
