Answer 1

1) приводим к общему знаменателю,это 90 - 52/90-48/90=4/90

2)

3)8/8 + 3/8=11/8=1 целая 3/8

4)1 целая 6/6 - 5/6 = 1 целая 1/6

5)1ц.5/5 + 3/5=1ц.8/5=2ц 3/5

Answer 2

Sure, I can help you with those arithmetic calculations. Here are the solutions to the expressions you provided:

1. 26/45 - 16/30 = 8/45
2. 13/18 - 5/24 = 11/36
3. 1 + 3/8 = 11/8
4. 2 - 5/6 = 7/6
5. 2 + 3/5 = 13/5
6. 3 - 10/17 = 41/17
7. 22 11/15 - 22 = 11/15
8. 12 9/25 + 7 32/50 = 20 11/50
9. 5 3/20 - 4 7/10 = 1 19/20
10. 11 1/4 + 3 7/10 = 14 1/20
11. 5/13 + 7/26 = 19/26
12. 11/63 - 1/9 = 2/21
13. 12/15 - 3/5 = 0
14. 5 + 4/9 = 49/9
15. 4 - 7/11 = 37/11
16. 2 + 4/7 = 18/7
17. 5 - 12/15 = 23/15
18. 13 11/12 - 10 = 7 11/12
19. 15 7/24 + 8 1/3 = 23 5/8
20. 4 4/15 - 2 1/30 = 2 13/30
21. 12 1/5 + 2 5/10 = 14 3/10

Please note that these results are simplified where possible. If you need any further assistance, feel free to ask.
