Answer 1

5) (9/22 + 1 12/33) * 1,32 - 8/13 * 0,1625 = 2,24
1) 9/22 + 1 12/33 = 27/66 + 1 24/66 = 1 51/66
2) 1 51/66 * 1,32 = 117/66 * 132/100 = 234/100 = 2,34
3) 8/13 * 0,1625 = 8/13 * 1625/10000 = 8/13 * 65/400 = 5/50 = 1/10 = 0,1
4) 2,34 - 0,1 = 2,24

6) (6 8/15 - 4 21/45) * 4,5 - 2 1/6 : 0,52 = 5 2/15
1) 6 8/15 - 4 21/45 = 6 24/45 - 4 21/45 = 2 3/45 = 2 1/15
2) 2 1/15 * 4,5 = 31/15 * 45/10 = 93/10 = 9 3/10
3) 2 1/6 : 52/100 = 13/6 * 100/52 = 100/24 = 4 4/24 = 4 1/6 
4) 9 3/10 - 4 1/6 = 9 9/30 - 4 5/30 = 5 4/30 = 5 2/15
