On a math test, k students in the class averaged 80%. The remaining students in the class,q students, averaged 94% on the test. The class average on the test was 88%. Express the ration of k/q in simplest form.

  • Algebra -

    80k + 94q = 88(k+q)
    80k + 94q = 88k + 88q
    6q = 8k
    k/q = 6/8 = 3/4
