Выполните вычитание:
1)4 1/30 - 3 1/20 = 121/30 - 61/20= 242/60 - 183/60 = 59/60
2)13 1/24 - 1 11/16 = 313/24 - 27/16 = 626/48 - 81/48 = 545/48
3)14 1/2 - 4 1/8 = 29/2 - 33/8 = 116/8 - 33/8 = 83/8
Вычислите:
1)2 3/5 - 2/5 = 13/5 - 2/5 = 11/5 = 2 1/5
2)12 3/5-2 = 10 3/5
3)4 3/5-3 2/5 = 23/5 - 17/5 = 6/5 = 1 1/5
