(17 23/47 + 5 24/47) - (18 5/13 - 6 12/13) = 11 7/13

1) 17 23/47 + 5 24/47 = 22 целых 47/47 = 23;

2) 18 5/13 - 6 12/13 = 17 18/13 - 6 12/13 = 11 целых 6/13;

3) 23 - 11 6/13 = 22 13/13 - 11 6/13 = 11 целых 7/13.

Ответ: 11 целых 7/13.

Verified answer

(17(23/47) + 5(24/47)) - (18(5/13) - 6(12/13))=150/13=11(7/13)
