Сложение и вычитание дробей с разными знаменателями 2/3-1/6 4/5+1/2 2/15+9/40 7/16-3/8 7/20-7/32 1/36+5/24

Verified answer

2/3 - 1/6 = 4/6 - 1/6 = 3/6 = 1/2
4/5 + 1/2 = 8/10 + 5/10 = 13/10 = 1 целая 3/10
2/15 + 9/40 = 16/120 + 27/120 = 43/120
7/16 - 3/8 = 7/16 - 6/16 = 1/16
7/20 - 7/32 = 56/160 - 35/160 = 21/160
1/36 + 5/24 = 4/144 + 30/144 = 34/144 = 17/72
