Question

On a true/false test, the ratio of true questions to false questions is 3 to 7. What is the ratio of true questions to total questions? 3 to 10 7 to 3 3 to 7 4 to 7

Answer 1

3 to 10

Explanation:

Since the ratio of true to false questions is 3:7, there are 3 true questions for every 7 false questions. This means that when there are 3 true questions, there are 7 false questions plus the 3 true questions meaning there are 10 questions in total. This results in a ratio of 3:10 true to total questions.
