Сумма 1 1/3 + 3 1/7 наибольшая

Пошаговое объяснение:

1 1/3 + 3 1/7 = 4/3 + 22/7 = 28/21 + 66/21 = 94/21 = 4 10/21

2 1/3 + 2 1/9 = 7/3 + 19/9 = 21/9 + 19/9 = 40/9 = 4 4/9

1/7 + 4 1/9 = 1/7 + 37/9 = 9/63 + 259/63 = 268/63 = 4 16/63

1 1/3 + 2 1/2 = 4/3 + 5/2 = 8/6 + 15/6 = 23/6 = 3 5/6

94/21 = 564/126

40/9 = 560/126

268/63 = 536/126

23/6 = 483/126
