mrs. karson's music class includes both 6th and seventh graders. the ratio's of 6th graders to students ine the class is 4:7. there are 9 seventh graders in the music class how many students sre in the class?

  • math -

    six graders --- 4x
    7th graders --- 7x
    x/y = 4/7

    given: 7x= 9
    x = 9/7

    uh, uh, looks like we have some "part-time students"

    Question is flawed, number of students must be whole numbers.
    Check your typing.
