(2 3/4 * 4 + 5 1/6 : 1/2 - 10 5/9 ) * 9

Question

(2 3/4 * 4 + 5 1/6 : 1/2 - 10 5/9 ) * 9

Answer 1

1) 2 3/4 * 4 = 11/4 * 4 = 11
2) 5 1/6 : 1/2 = 31/6 : 1/2 = 31/6 * 2/1 = 31/3 = 10 1/3 
3) 11 + 10 1/3 = 21 1/3 
4) 21 1/3 - 10 5/9 = 21 3/9 - 10 5/9 = 20 12/9 - 10 5/9 = 10 7/9
5) 10 7/9 * 9 = 97/9 * 9 = 97
Ответ: 97
