Question

Решить: а) 7/9: 14/27= б)2(целых)5/8: 3(целых)1/16 в)5(целых) 1/7: 3,6= заранее

Answer 1

$\frac{7}{9} \div \frac{14}{27} = \frac{7}{9} \times \frac{27}{14} = \frac{3}{2} = 1 \frac{1}{2} = 1.5$
2)
$2 \frac{5}{8} \div 3 \frac{1}{16} = \frac{21}{8} \times \frac{16}{49} = \frac{3 \times 2}{1 \times 7} = \frac{6}{7}$
3)
$5 \frac{1}{7} \div 3 \frac{3}{5} = \frac{36}{7} \times \frac{5}{18} = \frac{2 \times 5}{7} = \frac{10}{7} = 1 \frac{3}{7}$
