1) 3/8 * 2 2/3 = 2/8 * 8/3 = 1
2) (2 1/4 + 3 2/3) : (8,5 - 1 2/5) * 1,2 = 1
1) 2 1/4 + 3 2/3 = 2 3/12 + 3 8/12 = 5 11/12
2) 8,5 - 1 2/5 = 8,5 - 1,4 = 7,1 = 7 1/10
3) 5 11/12 : 7 1/10=71/12 * 10/71 = 10/12 = 5/6
4)5/6 * 1,2 = 5/6 * 12/10 = 1
3) 1 - 16/23 = 23/23 - 16/23 = 7/23
4) (3 1/3 * 1,3 - 7,2 * 2/27 - 9,1 : 3,5) : 2/5 = 3
1) 3 1/3 * 1,3 = 10/3 * 13/10 = 13/3 = 4 1/3
2) 72/10 * 2/27 = 8/15
3) 9,1 : 3,5 = 2,6
4) 4 1/3 - 8/15 = 4 5/15 - 8/15 = 3 20/15 - 8/15 = 3 12/15 = 3 4/5 = 3,8
5) 3,8 - 2,6 = 1,2
6) 1,2 : 2/5 = 1,2 : 0,4 = 3
