Question

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

Answer 1

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