"/" - это типо палка дроби

1) 18/45 = 2·9/5·9 = 2/5

2) 22/88 = 1·22/4·22 = 1 / 4

3) 12/36 = 1·12/3·12 = 1/3

4) 50/75 = 2·25/3·25 = 2 / 3

5) 30/105 = 2·15/7·15 = 2 / 7

6) 400/500 = 4·100/5·100 = 4 / 5

7) 88/990 = 4·22/45·22 = 4 / 45

8) 42/720 = 7·6/120·6 = 7 1/120

9) 100/25 = 4·25/25 = 4

10) 24/360 = 1·24/15·24 = 1 / 15
