Answer 1

$3\frac{1}{2} *1\frac{1}{32}*4\frac{5}{7}=\frac{7}{2}*\frac{4}{3}*\frac{33}{7} =\frac{1}{2}*\frac{4}{3}*33=\frac{2}{3}*33=2*11=22 \\\\ \frac{6}{25}*3\frac{3}{4}*\frac{8}{9}=\frac{2}{25}*\frac{15}{4}*\frac{8}{3}=\frac{2}{25}*15*\frac{2}{3}=\frac{2}{5}*3*\frac{2}{3}=\frac{2}{25}*2=\frac{4}{5}$

Answer 2

Пошаговое объяснение:

№15

1) 3 1/2 * 1 1/3 = 7/2 * 4/3 = 28/6 = 14/3

2) 14/3 * 4 5/7 = 14/3 * 33/7 = 2/1 * 11/1 = 22/1 = 22

№16

1) 6/25 * 3 3/4 = 6/25 * 15/4 = 3/5 * 3/2 = 9/10

2) 9/10 * 8/9 = 1/5 * 4/1 = 4/5
