Question

6/10 m +2/15m-3/5m+2/15m=
Если m =45 m=18 2/4

Answer 1

$frac{6}{10}m+frac{2}{15}m-frac{3}{5}m+frac{2}{15}m = frac{3}{5} m + frac{2}{15}m - frac{3}{5} m+ frac{2}{15} m = \ \ = frac{2}{15} m + frac{2}{15}m = frac{4}{15} m \ \ frac{4}{15} *45 = 4*3 =12 \ \ frac{4}{15} *18 frac{2}{4} = frac{4}{15}* frac{74}{4}=frac{74}{15}=4frac{14}{15}$
