Ответ:

4. 1/9

Пошаговое объяснение:

1) 4. 1/10 - 3. 4/15 = 4. 3/30 - 3. 8/30 = 3. 33/30 - 3. 8/30 = 25/30 = 5/6

2) 5/6 : 1. 1/5 = 5/6 : 6/5 = 5/6 * 5/6 = 25/36

3) 4. 1/10 : 1. 1/5 = 41/10 : 6/5 = 41/10 * 5/6 = 41/2 * 1/6 = 41/12 = 3. 5/12

4) 25/36 + 3. 5/12 = 25/36 + 3. 15/36 =

3. 40/36 = 4. 4/36 = 4. 1/9

Пошаговое объяснение:

( 4 1/10 - 3 4/15) : 1 1/5 + 4 1/10 : 1 1/5 = 4 1/9

1) 4 1/10 - 3 4/15 = 4 3/30 - 3 8/30 = 3 33/30 - 3 8/30 = 25/30 = 5/6

2) 5/6 : 1 1/5 = 5/6 : 6/5 = 5/6 * 5/6 = 25/36

3) 4 1/10 : 1 1/5 = 41/10 : 6/5 = 41/10 * 5/6 = 41/2 * 1/6 = 41/12 = 3 5/12

4) 25/36 + 3 5/12 = 25/36 + 3 15/36 = 3 40/36 = 4 4/36 = 4 1/9
