Question

Вычислите: 1) 21/40 : 3/4 2) 1 5/9 : 1 8/27 3) 5 : 15/16 4) 9/17 : 3

Answer 1

1) $frac{21}{40} : frac{3}{4} = frac{21}{40} * frac{4}{3} = frac{7}{10} = 0,7$
2) $1 frac{5}{9} : 1 frac{8}{27} = frac{14}{9} * frac{27}{35} = frac{42}{35} = 1 frac{7}{35} = 1,2$
3) $5 : frac{15}{16} = frac{5}{1} * frac{16}{15} = frac{16}{3} = 5 frac{1}{3}$
4) $frac{9}{17} : 3 = frac{9}{17} * frac{1}{3} = frac{3}{17}$
