Answer 1

1) 2 3/4 + 5/8 = 2 6/8 + 5/8 = 2 11/8 = 3 3/8
2) 3 3/8 * 4/9 = 27/8 * 4/9 = 3/2 = 1,5
3) 8 1/6 - 3 1/2 = 8 1/6 - 3 3/6 = 7 7/6 - 3 3/6 = 4 2/3
4) 4 2/3 : 1 1/6 = 14/3 : 7/6 = 14/3 * 6/7 = 4
5) 1,5 : 4 = 0,375
6) 4,8 - 1 2/5 = 4 8/10 - 1 2/5 = 4 8/10 - 1 4/10 = 3,4
7) 3,4 : 0,68 = 5
8) 2 1/2 + 1 1/8 = 2 4/8 + 1 1/8 = 3 5/8
9) 29 : 3 5/8 = 29 : 29/8 = 29 * 8/29 = 8
10) 5 : 8 = 0,625
11) 0,375 + 0,625 = 1
