Xio just took a math test with 25 questions, each worth an equal number of points. The test is worth 100 points total. If a score of 83 points earns a grade of B, how many questions would Xio need to get right to get a B on the test?
Each question is worth 4 points (100/25=4) Therefore, when you divide 83 by 4, you get 20.75, as as he's aiming to get a B, this needs to be rounded up to 21. Xio would need to get 21 questions right to get a B, hope this helps :)
