42 is 200 percent of what number?

So I put 42 over 100 is equal to 200 over x?
Is this right? Can someone explain?
Thank you

Close, but not exactly.

42 is 200% is the same as x is 100%, so
42/200 = x/100

Yes, you are on the right track! To find out what number 42 is 200 percent of, you can set up a proportion using the following equation:

200/100 = 42/x

In this equation, 200 represents 200 percent and 100 represents the whole or 100 percent. By setting up this proportion, you are essentially saying that 42 is equal to 200 percent of some number x.

To solve this proportion, you can cross-multiply:

200 * x = 100 * 42

This simplifies to:

200x = 4200

Now, you can isolate x by dividing both sides of the equation by 200:

x = 4200/200

x = 21

Therefore, 42 is 200 percent of 21.
