1/2 science
1/8 math
X reading

You have to convert to fractions to 24ths so...

1/2 will turn into 12/24

1/8 will turn into 3/24 because 24 divided by 8 = 3 so 1/8 times 3 give gives you 3/24

Then you add the 2 fractions so...

12/24 + 3/24 = 15/24

The rest of the kids are reading so...

24/24 - 15/24 = 9/24

Therefore 9 students are reading.
