One way is 8 + 8/8 = 9
Or if you mean three *eighths* of a number equals nine, you would write the following equation:
(3/8)n = 9
Then multiply both sides by 8/3:
n = 9 * 8/3
Multiply and simplify:
n = 72/3
n = 24

You mean "three eighTHs"? Just translate the problem into math: if your number is x, then 3/8 of it is (3/8)x. Set that equal to 9 and you get (3/8)x = 9. Solve for x by multiplying both sides by 8/3.

Hai Robby R,
Let the number = N
Then, (3/8)*N = 9
=> N = 9*(8/3) = 24

(3/8)x=9
so then 8/3 (3/8)x multiply by (8/3)
(8/3)(3/8)x=9(8/3)
^this one cancel's out so you're left with
x=24

selection abc = a*one hundred+b*10+c =>abc mod 9 = ((a*one hundred mod 9) + (b*10 mod 9) + c mod 9)mod 9 = (((a mod 9) x (one hundred mod 9))mod9 + ((b mod 9) x (10 mod 9))mod 9 + c mod 9) mod 9 = (a mod 9 + b mod 9 + c mod 9) mod 9 = (a+b+c) mod 9 = 0 if a+b+c could be divided via 9

(3/8)N = 9
N=9(8/3)
N=72/3
