Question

(48 целых : 45 - 1/3) * 2 целых 3/11 + 3/ 5

Answer 1

(48 : 45 - 1/3) * 2 целых 3/11 + 3/5 = 2 целых 4/15

1) 48 : 45 = 48/45 = 1 целая 3/45 = 1 целая 1/15
2) 1 целая 1/15 - 1/3 = 1 целая 1/15 - 5/15 = 16/15 - 5/15 = 11/15
3) 11/15 * 2 целых 3/11 = 11/15 * 25/11 = (1*5)/(3*1) = 5/3 = 1 целая 2/3
4) 1 целая 2/3 + 3/5 = 1 целая 10/15 + 9/15 = 1 целая 19/15 = 2 целых 4/15
