Question

решите уравнение: 11 целых 7/9+у=13 целых1/18

Answer 1

$11\frac79+y=13\frac1{18}\\y=13\frac1{18}-11\frac79\\y=13\frac1{18}-11\frac{14}{18}\\y=1\frac5{18}$

Answer 2

$11 \frac{7}{9} + y = 13 \frac{1}{8}$
$\frac{106}{9} + y = \frac{105}{8}$
$y = \frac{105}{8} - \frac{106 }{9}$
$y = \frac{97}{72}$
$y = 1 \frac{25}{72}$
