Katrina’s memory card is taken up by 5⁄8 photos and 1⁄4 videos. How much storage does the memory card have left?

To find out how much storage Katrina's memory card has left, we first need to add up the fractions that represent the storage taken up by photos and videos.

The fraction representing the storage taken up by photos is 5/8 and the fraction representing the storage taken up by videos is 1/4.

To add these fractions, we need to find a common denominator. The least common denominator for 8 and 4 is 8. So we can rewrite 1/4 as 2/8.

Now we can add the fractions: 5/8 + 2/8 = 7/8.

This means that 7/8 of the memory card's storage is taken up by photos and videos.

To find out how much storage is left, we subtract this fraction from 1 (since 1 represents the whole memory card).

1 - 7/8 = 1/8.

So, Katrina's memory card has 1/8 of its storage left.
