A bookcase has 3 shelves with a total of 24 books. The top shelf has 8 mystery books. The middle shelf has 10 math books. The bottom shelf has 6 science books. Two books are now taken off each shelf. What fraction of the books remaining on the three shelves are math books? Express your answer as a common fraction.

Start off by subtracting 2 from 10, which is 8.

 

Subtract 6 from 24 as two books are taken off each of the 3 shelves. 

 

This leaves us with 8/18, which simplifies to 4/9.

 

Please correct me if I'm wrong smiley.
