Question

(12.2/3-63.1/3:5.2/11)*(2,25+2.2\5:1.1/15)*6:15 __________________________________+13/19 3

Answer 1

(12.2/3-63.1/3:5.2/11)*(2,25+2.2\5:1.1/15)*6:15 

                               

1) 63 1/3 : 5 2/11 = 190/3 * 11/57 = 110/9

2) 12 2/3 - 110/9 = 38/3 - 110/9 = 4/9

3) 2 2/5 : 1 1/15 = 12/5 * 15/16 = 9/4 = 2,25

4) 2,25 + 2,25 = 4,5

5) 4/9 * 45/10 = 10/5 = 2

6) 2 * 6 = 12

7) 12 : 15 = 0,8

8)

Дальше не могу понять, запись не корректна. К чему относится __________________________________+13/19 3 ?
