Answer:
8/10 ( you didnt say how much questions there were)
Step-by-step explanation:
As a fraction, 80/100 simplifies to be 8/10. ( 10 can go into 80, 8 times and 10 can go into 100, 10 times)
So, if Brianna had 10 questions on the test and answered 80% correctly, take the numerator of this simplified fraction and that's the answer

Brianna got 8 questions correct
