Question

(6,9+2 11/20)*2 3/5-3,5*2,7

__________________________=

8 1/9-(2 1/12-1 1/18):9 1/4

Answer 1

1) 6,9+2 11/20 = 6,9 + 2,55 = 9,45

2) 9,45 * 2 3/5 = 9,45 * 2.6 = 24.57

3) 3.5 * 2.7 = 9.45

4)24.57 - 9,45 = 15.12

5)2 1/12-1 1/18 = 37/36

6)37/36 : 9 1/4= 37/36 : 37/36 = 1

7)8 1/9- 1= 7 1/9

8)15.12 -  7 1/9 = 8.01
