Solve ratios

1. Look for number that can go through both numbers

I: 22: 40, divide both sides by 2

11:20. 

ii: 8: 13

This is already in it's simpliest form because no same can divide them 

III: 30:45, divide both sides by 3 

10: 15 

Divide both sides by 5 

2:3. 

iv: 16: 68, divide both sides by 2 

8: 34 

Divide both by 2 

4:17. 

v: 3: 5: 9/2, 

This is already in it's simpliest form 

vi: 48:63, divide both sides by 3 

16:21. 

vii: 2.5:4.5:6 

This is already in it's simpliest form.
