Troy took a total of 12 quizzes over the course of 3 weeks. How many weeks of school will Troy have to attend this quarter before he will have taken a total of 24 quizzes? Solve using unit rates.

6

Step-by-step explanation:

First you divide 12 by 3 getting 4 showing that he took 4 quizzes a week. Now you know the amount of the quizzes he takes a week. Divide the 24 by 4 you get 6 if he takes 4 quizzes a week then it must take his 6 weeks to take all 24. another way is you see that 24 is the double of twelve right? Now double the 3 weeks and and you get six.
