Question

1целая 1/35 поделить на 18 56 : 14/15 53/63 : 29/42

Answer 1

$1 \frac{1}{35} \div 18 = \frac{36}{35} \div \frac{18}{1} = \frac{36}{35} \times \frac{1}{18} = \frac{36 \times 1}{35 \times 18} = \frac{2 \times 1}{35 \times 1} = \frac{2}{35}$

$56 \div \frac{14}{15} = \frac{56}{1} \times \frac{15}{14} = \frac{56 \times 15}{1 \times 14} = \frac{4 \times 15}{1 \times 1} = \frac{60}{1} = 60$

$\frac{53}{63} \div \frac{29}{42} = \frac{53}{63} \times \frac{42}{29} = \frac{53 \times 42}{63 \times 29} = \frac{53 \times 2}{3 \times 29} = 1 \frac{19}{87}$
