Question

Знайди частку 4 2/3:8/9;
3 1/3:2 6/7​

Answer 1

Ответ:

$4\frac{2}{3} :\frac{8}{9} =\frac{14}{3} :\frac{8}{9} =\frac{14*9}{3*8}=\frac{7*3}{1*4}=\frac{21}{4} =5\frac{1}{4} =5,25$

$3\frac{1}{3} :2\frac{6}{7} =\frac{10}{3} :\frac{20}{7} =\frac{10*7}{3*20}=\frac{7}{3*2}=\frac{7}{6}=1\frac{1}{6}$
