  • 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.
