#10# questions

To simplify this question, we are basically asking this:

"#4/5# of what number of questions equals the #8# questions she completed?"

Realizing this, we can easily derive an equation from the information.

#4/5x=8#

Now all we do is solve:

#4/5x=8#

#x=8/(4/5)#

#x=(8/1) * (5/4)#

#x=40/4#

#x=10# questions
