Question

1 1/5:1/5 2 1/2:1 2/3 1 1/5*1/6 1 12* 1 13 решите

Answer 1

$1 frac{1}{5} div frac{1}{5} = frac{6}{5} times 5 = 6 \ \ 2 frac{1}{2} div 1 frac{2}{3} = frac{5}{2} div frac{5}{3} = frac{5 times 3}{2 times 5} = frac{3}{2} = 1 frac{1}{2} = 1.5$

▪

$1 frac{1}{5} times frac{1}{6} = frac{6 times 1}{5 times 6} = frac{1}{5} \ \ 1 frac{1}{2} times 1 frac{1}{3} = frac{3 times 4}{2 times 3} = frac{4}{2} = 2$
