1)3целых1/9: х=72)5/7: 2/3=3)1целая10/36*1целую2/25=

Answer 1

1.

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

2.

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

3.

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