Of the 100 donated gift baskets, you raffled off 97. What fraction of the baskets are left?

Nesterboy [21]

There are 100 baskets in total. 97 were raffled off. This means you'll want to subtract 97 from 100.

Let's turn those numbers into an equation:

100/100 - 97/100 = ?

100 - 97 = 3

So, ? = 3/100

3/100 cannot be simplified.
