Question

1)3целых1/9:х=7
2)5/7:2/3=
3)1целая10/36*1целую2/25=

Answer 1

1.

$3frac{1}{9} = frac{27}{9} \ x = frac{27}{9} div 7 = frac{27}{9 times 7} = frac{3}{7}$

2.

$frac{5}{7} div frac{2}{3} = frac{5 times 3}{7 times 2} = frac{15}{14}$

3.

$1 frac{10}{36} = frac{46}{36} \ 1 frac{2}{25} = frac{27}{25} \ frac{46 times 27}{36 times 25} = frac{621}{450} = 1.38$
