2/7 + 3/7 = 5/7
2/3 + 2/9 = 6/9 + 2/9 = 8/9
3/5 + 3/7 = 21/35 + 15/35 = 36/35 = 1 1/35
1/6 + 3/8 = 4/24 + 9/24 = 13/24
17/5 = 3 2/5
10/6 = 1 4/6 = 1 2/3
3 7/10 км = 37/10 * 1000 = 37000/10 = 3700 метров
2 1/4 часа = 9/4 часа * 60 = 135 минут
5 + 7/9 = 5/1 + 7/9 = 45/9 + 7/9 = 52/9 = 5 7/9
3 3/4 + 1 1/2 = 15/4 + 3/2 = 15/4 + 6/4 = 21/4 = 5 1/4
