Question Zachary has 25 country music CDs, which is one-fifth of his CD collection. How many CDs does Zachary have?

Zachary has a total of 125 CDs in his collection! Since 25 is one-fifth of the total, you can simply multiply 25 by 5 to find the complete set. Math can be like a country song, where you follow the rhythm to find the right answer! When tackling similar problems, a common mistake is to forget to multiply properly. It’s easy to get lost in the numbers, so always double-check your math by reversing the calculation—if you multiply your final answer by one-fifth, should you get back to 25? It’s like a good chorus; make sure it sticks!
