помогите решить с обяснениям пж

Answer 1

Пошаговое объяснение:

№1

1) 3. 1/4 + 2. 1/6 = 3. 3/12 + 2. 2/12 = 5. 5/12

2) 5. 5/12 : 2. 3/5 = 65/12 : 13/5 = 65/12 * 5/13 = 5/12 * 5/1 = 25/12 = 2. 1/12

3) 2. 1/6 : 13 = 13/6 * 1/13 = 1/6

4) 1/6 + 2. 1/12 = 2/12 + 2. 1/12 = 2. 3/12 = 2. 1/4

№2

1) 7. 1/3 - 6. 7/8 = 7. 8/24 - 6. 21/24 = 6. 32/24 - 6. 21/24 = 11/24

2) 11/24 : 3/4 = 11/24 * 4/3 = 11/6 * 1/3 = 11/18

3) 23 + 11/18 = 23. 11/18

4) 23. 11/18 - 5. 1/4 = 23. 22/36 - 5. 9/36 = 18. 13/36
