I get 9 for this one.

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.
