Answer 1

4 2/3 + 1 1/2 = 4 4/6 + 1 3/6 = 5 7/6 = 6 1/6
1 3/5 - 1/2 = 1 6/10 - 5/10 = 1 1/10
3 1/4 - 1 5/6 = 3 3/12 - 1 10/12 = 1 5/12
2/3 * 1/4 = 2/12 = 1/6
2/3 * 6/7 * 7/8 = 84/168 = 1/2
4 * 2 3/8 = 4/1 * 19/18 = 78/18 = 4 
1 5/7 * 4 2/3 = 4 10/21
4/9 : 2/27 = 4/9 * 27/2 = 108/18 = 6 
4/5 : 1 1/5 = 4/5 * 5/6 = 20/30 = 2/3
2 : 2/3 = 2/1 * 3/2 = 6/2 = 3
4/5 : 4 = 4/5 * 1/4 = 4/20 = 1/5

2,2 + 1/4 = 2,2 + 0,25 = 2,45
1/6 + 0,5 = 1/6 + 1/2 = 1/6 + 3/6 = 4/6 = 2/3
3,4 - 3/4 = 3,4 - 0,75 = 2,65
2 1/3 - 0,5 = 2 1/3 - 1/2 = 2 2/6 - 3/6 = 1 5/6
1/10 * 0,47 = 0,1 * 0,47 = 0,047
1,3 * 8/26 = 1 3/10 * 8/26 = 1 24/260 = 1 12/130
1/2 : 1,5 = 1/2 : 1 1/2 = 1/2 * 2/3 = 2/6 = 1/3
0,8 : 2/3 = 8/10 : 2/3 = 8/10 * 3/2 = 24/20 = 1 4/20 = 1 1/5
0,1 * 4,5 +0,5 : 0,1 + 4 = 13,5
0,2 * 1/2 : (2,5 + 1/4) = 1/5 * 1/2 = 2/10 * 5/10: 10/100 = 1/10 : 2 3/4 = 1/10 * 4/11 = 4/110 = 2/55
