Question

1) 1 целых 5/12:2/15 ; 2)1/8: 1 целых 7/12!​

Answer 1

$1 \frac{5}{12} \div \frac{2}{15} = \frac{1 \times 12 + 5}{12} \times \frac{15}{2} = \frac{17}{4} \times \frac{5}{2} = \frac{17 \times 5} {4 \times 2} = \frac{85}{8} = 10 \frac{5}{8}$$\frac{1}{8} \div 1 \frac{7}{12} = \frac{1}{8} \times \frac{7}{12} = \frac{1 \times 7}{8 \times 12} = \frac{7}{96}$
