Математика: :1 целая 1/3 + 730 + 2 целых 3/5 2. 2 целых 5/6- (1 целая 1 1/3 - 1/2) 3. 1целых 1/2 - 3/4 + 7/8

Raffee · Answer

1 1/3 + 730 + 2 3/5 = 733 + 1/3 + 3/5 = 733 + 5/15 + 9/15 = 733 целых 14/15

2 5/6 - (1 1/3 - 1/2) = 2 5/6 - (1 2/6 - 3/6) = 2 5/6 - 1 2/6 + 3/6 =
= 1 целая (5-2+3)/6 = 1 целая 6/6 = 2

1 1/2 - 3/4 + 7/8 = 1 4/8 - 6/8 + 7/8 = 1 целая + (4-6+7)/8 = 1 целая 5/8
