You need to divide both sides of the ratio by the same amount. To get from 4 on the right to 2 on the right divide by 2 so 2 on the left is also divided by 2 to get 1. 2:4 = 1:2

Hi Calilove, you have some good suggestions below on how to solve your problem. What I want to add is that you can work with your strengths whether that is fractions or ratios. I have lots of experience explaining fractions, decimals, percentages and ratios. Let me know if you would like any further help.

This is dealing with basic probability and I think when dealing with ratios as in this problem the solution is 2:4 =  4:2

Hello. We have to find the highest common factor (HCF) of 2 and 4 and divide both 2 and 4 by it. The HCF is 2. After division, we get 1:2.

Hi Calilove, Making equivalent ratios are easy. It is just like equivalent fractions. Step 1: Let's first look at the two ratios.  LEFT : RIGHT   2  : 4     _  : 2 They are in proportion. First ratio is twice in value than the second ratio. Step 2: Look at the right hand side of your first ratio. You have 4. If you divide this number by 2 you will get the right hand side of your second ratio. Step 3: You do the same for the number on the left hand side of each ratio. You divide this left hand side by 2. The answer will be 1. 2  : 4 1  : 2
