Answer 1

$\displaystyle 4\frac{5}{12}-1\frac{1}{2}:(2\frac{1}{6}+\frac{8}{15})*1\frac{3}{10}=\frac{53}{12}-\frac{3}{2}:(\frac{13}{6}+\frac{8}{15})*\frac{13}{10}=\frac{53}{12}-\frac{3}{2}:\frac{27}{10}*\frac{13}{10}=\\ \\ \frac{53}{12}-\frac{3}{2}*\frac{10}{27}*\frac{13}{10}=\frac{53}{12}-\frac{1}{2}*\frac{1}{9}*13=\frac{53}{12}-\frac{13}{18}=\frac{133}{36}=3\frac{25}{36}$

Answer 2

Пошаговое объяснение:

1) 2. 1/6 + 8/15 = 2. 5/30 +

16/30 = 2. 21/30 = 2. 7/10

2) 1. 1/2 : 2. 7/10 = 3/2 : 27/10 = 3/2 * 10/27 = 1/1 * 5/9 = 5/9

3) 5/9 * 1. 3/10 = 5/9 * 13/10 = 1/9 * 13/2 = 13/18

4) 4. 5/12 - 13/18 = 4. 15/36 - 26/36 = 3. 51/36 - 26/36 = 3. 25/36

Ответ: 3. 25/36
