Question

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?

Answer 1

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 :)

Answer 2

So, Xio wants a B for his math test.

Well, each question is worth 4 points

You divide 83 by 4 which will equal 20.75. (Round up)

If he wants the B for his math test, Xio will need to get 21 questions correct.

Hope I helped!
