bibby · Answer

First set up the proportion.$$\frac{ incorrect }{ correct } = \frac{ 4 }{ 20-4 }$$

anonymous · Answer

wich equals 1/5 right

anonymous · Answer

Can u help me next bibby with my new open question

bibby · Answer

This isn't asking incorrect/total questions. Always reread the question twice.

4/20 = 1/5. but you didn't get 20 correct. you got 16 correct.

as such your ratio is 4/16

bibby · Answer

uh yeah. message me next time and don't hijack other peoples questions

anonymous · Answer

Sorry im new to this site

anonymous · Answer

wait so 1/5 isn't the answer
 it 4/16 ?

bibby · Answer

Yeah. It's a misleading question.
$$\frac{ incorrect answers }{ correct answers } = \frac{ 4 }{ 20-4 } = \frac{ 4 }{ 16 } = \frac{ 1 }{ 4 }$$
