Question

ПОМОГИТЕ СРОЧНО Вычислите разность. 1 целая 1/4 - 1/3, 1целая 2/3 - 5/6 , 3 целых 1/4 - 5/6.4 целых 1/5 - 2 целых 3/10 , 2 целых 2/7 - 1 целая 3/5 , 4 целых 1/6 - 1 целая 2/3

Answer 1

11/12, 5/6, 2 целых 5/12, 1 целая 9/10, 24/35, 2 целых 1/2

Answer 2

1 целая 1/4 - 1/3 = (4/4 + 1/4) - (3/3) = 5/4 - 3/3 = (5/4 * 3/3) - (3/3) = 15/12 - 3/3 = 15/12 - 4/4 = (15 - 4) / 12 = 11/12

1 целая 2/3 - 5/6 = (3/3 + 2/3) - (5/6) = 5/3 - 5/6 = (5/3 * 2/2) - (5/6) = 10/6 - 5/6 = (10 - 5) / 6 = 5/6

3 целых 1/4 - 5/6 = (12/4 + 1/4) - (5/6) = 13/4 - 5/6 = (13/4 * 3/3) - (5/6) = 39/12 - 5/6 = (39 - 10) / 12 = 29/12

4 целых 1/5 - 2 целых 3/10 = (20/5 + 1/5) - (2 * 10/10 + 3/10) = 21/5 - (20/10 + 3/10) = 21/5 - 23/10 = (21/5 * 2/2) - (23/10) = 42/10 - 23/10 = (42 - 23) / 10 = 19/10

2 целых 2/7 - 1 целая 3/5 = (14/7 + 2/7) - (1 * 5/5 + 3/5) = 16/7 - (5/5 + 3/5) = 16/7 - 8/5 = (16/7 * 5/5) - (8/5) = 80/35 - 8/5 = (80 - 56) / 35 = 24/35

4 целых 1/6 - 1 целая 2/3 = (24/6 + 1/6) - (1 * 2/2 + 2/3) = 25/6 - (2/2 + 2/3) = 25/6 - 4/3 = (25/6 * 3/3) - (4/3) = 75/18 - 4/3 = (75 - 24) / 18 = 51/18 = 17/6
