Question

Вычислите:
1 1/12 + (-5 1/6)

3 2/15 + (-9 1/3)

Answer 1

$1 \frac{1}{12} + ( - 5 \frac{1}{6} ) = 1 \frac{1}{12} - 5 \frac{1}{6} = 1 \frac{1}{12} - 5 \frac{2}{12} = - 4\frac{1}{12}$
$3 \frac{2}{15} + ( - 9 \frac{1}{3} ) = 3 \frac{2}{15} - 9 \frac{1}{3} = 3 \frac{2}{15} - 9 \frac{5}{15} = - 6 \frac{3}{15} = - 6 \frac{1}{5} = - 6.2$
