Відповідь:

Покрокове пояснення:

3/8 + 1/4 + 5/12 = 9/24 + 6/24 + 10/24 = 25/24 = 1 1/24

1/2 + 1/3 - 2/5 = 15/30 + 10/30 - 12/30 = 13/30

5/6 - 3/16 + 5/12 =   40/48 - 9/48 + 20/48 = 51/48 = 1 3/48 = 1/16

2/3 - 2/5 + 1/4 = 40/60 - 24/60 + 15/60 = 31/60

7/15 + 2/5 - 2/3 = 14/30 + 12/30 - 20/30 = 6/30 = 1/5

1/4 + 5/6 - 5/12 = 3/12 + 10/12 - 5/12 = 8/12 = 2/3
