Question

найти значение частного. 6/25:3/5; 8/15:20/21; 14/15:28/33; 39/43:13/43

Answer 1

$\frac{6}{25} \div \frac{3}{5} = \frac{6 \times 5}{25 \times 3} = \frac{2}{5} \\ \frac{8}{15} \div \frac{20}{21} = \frac{8 \times 21}{15 \times 20} = \frac{2 \times 7}{5 \times 5} = \frac{14}{25} \\ \frac{14}{15} \div \frac{28}{33} = \frac{14 \times 33}{15 \times 28} = \frac{11}{10} = 1 \frac{1}{10} \\ \frac{39}{43} \div \frac{13}{43} = \frac{39 \times 43}{43 \times 13} = 3$
