Алгебра: 2,0125 +2 3/16 / 2/3-1/5

Решите задачу:

$2,0125+2 \frac{3}{16} : \frac{2}{3} - \frac{1}{5} =5 \frac{3}{32}$
$1) 2 \frac{3}{16} : \frac{2}{3} = \frac{35}{16}* \frac{3}{2} = \frac{105}{32} =3 \frac{9}{32}$
$2) 3 \frac{9}{32} - \frac{1}{5} = \frac{105}{32} - \frac{1}{5} = \frac{525-32}{160} = \frac{493}{160} =3 \frac{13}{160}$
$3) 3 \frac{13}{160} +2,0125 =\frac{493}{160} + \frac{20125}{10000} = \frac{493}{160} + \frac{161}{80} = \frac{493+322}{160} = \frac{815}{160} = \frac{163}{32} =$ $=5 \frac{3}{32}$
