1/9 = a / a + 24 solve for a

  • 8th grade math -

    do you mean 1/9 = a /(a + 24) ?

    just cross multiply! i.e. multiply the numerator of one side by the denominator of the other side

    (1)(a+24) = 9(a)

    solve for a.

  • 8th grade math -

    a+24=9a
    24=9a-a
    24=8a
    8a=24 Divided with 8
    a=3

    Cheking:

    3/(3+24)=3/(27)= 3/(3*9)= 1/9
