Answer 1

Ответ:

Пошаговое объяснение:

1) $11* 4 \frac{17}{31}= 11* \frac{141}{31}= \frac{1551}{31}=50 \frac{1}{31}$

2) $52 \frac{2}{3}: 13=\frac{158}{3}: 13= \frac{158}{3}*\frac{1}{13} = \frac{158}{39}= 4 \frac{2}{39}$

Answer 2

1.

$11 \times 4\frac{17}{31} = \frac{11}{1} \times \frac{141}{31} = \frac{11 \times 141}{1 \times 31} = \frac{1551}{31} = 50 \frac{1}{31}$

2.

$52 \frac{2}{3} \div 13 = \frac{158}{3} \div \frac{13}{1} = \frac{158 \times 1}{3 \times 13} = \frac{158}{39} = 4 \frac{2}{39}$
