Question

Raven usually does 5 out of every 7 math problems correctly. Which table accurately shows how many math problems she will do correctly out of 14, 21, or 28 total problems?

Answer 1

B.

Explanation:

The proportions should be exactly the same for each set of questions and correct questions.

Based on Raven's history, she get 5 of 7.

Choice B. shows exactly that with a scalar of 2, 3, and 4. For Row 2, the set is twice as large, so Raven gets exactly twice as many questions correct and exactly twice as many incorrect.

For Option B., the
`(correct)/(total)` always simplifies to
`(5)/(7)` for every row.
