Please help

There are 2 answers for this (use a comma to separate them)

Emma got 90% of the questions on her history test correct if she answered 27 questions correctly, how many questions did Emma get wrong?

There were (A) questions on the test so she got (B) questions wrong

Answer 1

Explanation:

we can make it as a ratio

90/100=27/total Q

total Q= (27*100)/90=30

So wrong questions=30-27=3
