Answer:
3:1 = 6:2 (x=2)
Step-by-step explanation:
Think of ratios as a fraction
3/1 = 6/x
to get from 3 to 6 you multiply it by 2. now for the ratio to be the same, you have to multiply the denominator by 2 as well. 2 x 1 = 2. therefore it would be 6/2. you can notice that if you simplify it, it is equal to 3/1. it is the same thing with ratios.
