Question

Suppose you got 70% of the questions on your last test correct. if there were 90 equally weighted questions on the test, what was your ratio of correct to incorrect answers on the test? write your answer in lowest terms.

Answer 1

To find the ratio of correct to incorrect answers, multiply the percentage of correct answers by the total number of questions. The ratio is then simplified.

Step-by-step explanation:

To find the ratio of correct to incorrect answers, we first need to determine the number of questions that were answered correctly and incorrectly.

Given that the student got 70% of the questions correct, we can calculate the number of correct answers as 70% of 90 questions, which is 0.7 * 90 = 63.

Therefore, the ratio of correct to incorrect answers is 63:27, which can be simplified to 7:3.
