Answer 1

Ответ:

a) 1/2 + 1/3 + 5/6 = 3/6 + 2/6 + 5/6 = 10/6 = 5/3

b) 3/5 + 2/3 + 1/15 = 9/15 + 10/15 + 1/15 = 20/15 = 4/3

a) 1/2 + 3/4 + 5/8 = 4/8 + 6/8 + 5/8 = 15/8

3/4 - 1/8 + 5/12 = 9/8 - 1/8 + 5/12 = (9 - 1 + 5)/8 = 13/8

b)

2/3 + 1/6 - 2/15 = 10/15 + 2/15 - 2/15 = 10/15 = 2/3

c)

1/2 - 1/5 - 2/15 = 7/10 - 2/15 = 21/30 - 4/30 = 17/30
