Answer 1

$2,0125+2 frac{3}{16} : frac{2}{3} - frac{1}{5} =5 frac{3}{32}$
$1) 2 frac{3}{16} : frac{2}{3} = frac{35}{16}* frac{3}{2} = frac{105}{32} =3 frac{9}{32}$
$2) 3 frac{9}{32} - frac{1}{5} = frac{105}{32} - frac{1}{5} = frac{525-32}{160} = frac{493}{160} =3 frac{13}{160}$
$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}$
