18 over 9 = 2 so x over 6 = 2 making x = 6 x 2 ie 12
1/9=x/18 18=9x 2=x
You need to be careful in how you write such questions as it is important to know if you mean: x - 12/2 = 18 or (x-12)/2 = 18 If x - 12/2 = 18 then x = 18 + 12/2 x = 18 + 6 x = 24 If (x-12)/2 = 18 then x - 12 = 18 * 2 x - 12 = 36 x = 36 + 12 x = 48
2 over 3 = 18 over x+5... x=22 because (x+5) needs to equal 27 for the equation to be true.
1/2 x 18 is 9
X=18
9
4/9 x 2/2 = 8/18 5/18 + 8/18 = 13/18
2/5 x 45 = 18
If you mean 18 x 1/2 it equals 9
18 ÷ 9 x 2 = (18 ÷ 9) x 2 = 2 x 2 = 4
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1
