One-eighth of a bookstore's magazines are sold on a Friday. If 1/4 of the remaining magazines are sold the next day, what fractional part of the magazines remains at the end of the second day?

5/8

Step-by-step explanation:

These types of problems only require you to know how to make fractions similar in denominators (or the GCF).

If one-eighth of the store’s books are sold and then the next day 1/4 of the store’s books are sold then we simply only need to add the fractions and minus them from 1.

To do this we need to make 1/4 into an eighth. The GCF between 4 and 8 is 8 because you can multiply 4 by 2 to get 8, therefore you need to multiply 1/4 by 2/1 (or just 2). 1/4*2/1= 2/8.

Now that we know what 1/4 is in eights we want to add 2/8 to 1/8 which would be 2/8+1/8=3/8. Now we minus 3/8 from 1 to get our remaining amount of storage. Now all we need to do is think how much eighths is one, to do this just think what divided by 8 is one, which would be 8. 8/8=1. Therefore, 8/8-3/8=5/8.

c. (3,2,6) is the answer.
