Question

Emmy learned to sing a total of 12 pieces over the course of 6 weeks of voice lessons. How many weeks of lessons will Emmy need before she will be able to sing a total of 14 pieces? Assume the relationship is directly proportional.

Answer 1

7 weeks.

Explanation:

It took Emmy six weeks of vocal lesson to learn twelve pieces. If you divide 12÷6 it equals 2 or if you multiply 6×2 it equals 12, just like that if you divide (14÷7=2) or multiply (7×2) you will get the answer. you can also divide first and then multiply to check the answer/vice-versa.
