93x/100 = 45

Multiply throughout by 100,

93x = 4500

Dividing throughout by 93,

x = 4500/93 = 1500/31 = 48 12/31 ≈ 48.38

Let the number that is 93% of 45 be X.

`X*93/100` = 45

=> X = `4500/93`

45 is 93% of `4500/93` .

Let x be the number whose 93% is 45

93% of x = x*93/100 and this is equal to 45, given.

x*93/100 = 45, multiplying both sides with 100/93 we get: 

x = 45*100/93 =4500/93

or x= 48.387 approximately

45 is 93% of 4500/93 or 48.387 approximately

These solutions seem unnecessarily complicated.

45 divided by .93 = 48.38

45 is 93% of what? 

Write algebraically: 

45 = (93/100)x = .93x

x = 45/.93

x = 48.387....

So 93% is the same as .93 and when you have "of" in a math problem it usually stands for multiplication. Now we don't know what the original number being multiplied to .93 is so we substitute that with a variable x. And we know that the result is 45

So it would look something like this:

.93x= 45

Now we want to isolate the X on the left and move everything to the right to find X's value 

So we divide by .93

X=45/.93

Then simplify

X= 48.39. Approximately

45 is 93% of x

`93/100=45/x`

`93x=4500`

`x=48.39 ` would be your approximately the answer.

45 is 93%  :

Your equation should look like :

45/x = 93/100 multiply 93 with x and 45 with 100

By multiplying, you should get

4500 = 93x divide both sides by 93

By dividing, you should get

4500/93 = x

so your answer is about 48.39
