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
