Knowing this, we technically have two ratios in this question: 5:2 and 20:w (whereas 'w' represents the unknown number of wrong answers)
Can you sort of guess where this is going? We have to "unsimplify" the 5:2 ratio in order to find what 'w' is.
In order to turn 5 into 20, we simply have to multiply both sides by 4.
5:2 = 20:8
Looks like we've found our answer.
