30 % * X=200 (it is given)
or 30*X/100 =200
or X=200*100/30
and X=666.6667 It is the Ans

200 = 30% * X
Multiply both sides by 1/30%
200/30% = (30% * X)/30%
Cancel out the 30% on the right side because 30%/30% is = 1
then, 200/30% = X
Explanation: 200 is only 30% of X, with this we know that X is much larger than the 200. 30% is equivalen to 0.30 (30% /100% = 0.30)
So 200 / 0.30 is the X

200 is 30% of X ??
200 = 0.30x
x = 666.6666666666666666666667

200 = 30%
So you find 10%
200/3 Gives you 10%
which is 66.6r
then multiply that by ten to find 100%
Which Is 666.6r

200 = .30 X
200/.30 = X
666.67 = X

30% = 30/100
200 / x = 30 / 100
200 * 100 = 30 * x
200 * 100 / 30 = x
20000 / 30 = x
666.7 = x
Check this: 200/666.7 = 0.3, which is 30/100.

30%=.3
200=.3x (200 is 30% of x)
Solve for x:
200/.3=x

x * 0.3 = 200
<=>
x = 200 / 0.3
<=>
x = 2000 / 3

30%*x=200
x=200/30%
x=2000/3
