Simplify the following ratios:
8:12
4:8
2:10

2:3 1:2 1:5

Step-by-step explanation:

As you can see each of these are divisible by two. So just divide eache number in the ratio by two. If they are both STILL divisible by two then just divide them both by two again.

Ex: 8:12  8 divided by two is 4          4:6  Divide again to get 2:3

               12 divided by two is 6
