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

8th grade math  TutorCat, Wednesday, October 20, 2010 at 1:40am
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.

a+24=9a
24=9aa
24=8a
8a=24 Divided with 8
a=3
Cheking:
3/(3+24)=3/(27)= 3/(3*9)= 1/9
