Answer:
25 questions
Step-by-step explanation:
First set up the equation.
[tex]\frac{20}{x} = \frac{80}{100}[/tex]
To get from 20 to 80 you have to multiply by a scale factor of 4, so do the same to the bottom as well.
Do the inverse and divide 100 by 4 to get x = 25.
There were 25 questions on Victoria's test.
