Answer 1

$\frac{4}{15} + \frac{3}{4} = \frac{61}{60}$$\frac{5}{6} - \frac{9}{14} = \frac{16}{84} = \frac{4}{21}$$4 \frac{4}{7} + 6 \frac{1}{4} = \frac{32}{7} + \frac{25}{4} = \frac{303}{28} = 10 \frac{23}{28}$$5 \frac{7}{8} - 3 \frac{5}{6} = \frac{47}{8} - \frac{23}{6} = \frac{98}{48} = \frac{49}{24} = 2 \frac{1}{24}$

Answer 2

Пошаговое объяснение:

1) 4/15 + 3/4 = 16/60 + 45/60 = 61/60 = 1. 1/60

2) 5/6 - 9/14 = 35/42 - 27/42 = 8/42 = 4/21

3) 4. 4/7 + 6. 1/4 =

4. 16/28 + 6. 7/28 =

10. 23/28

4) 5. 7/8 - 3. 5/6 =

5. 21/24 - 3. 20/24 =

2. 1/24
