What is 17.5 percent of 1992 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 1992 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 1992 is 100%, so we can write it down as 1992=100%.
4. We know, that x is 17.5% of the output value, so we can write it down as x=17.5%.
5. Now we have two simple equations:
1) 1992=100%
2) x=17.5%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
1992/x=100%/17.5%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 17.5% of 1992

1992/x=100/17.5
(1992/x)*x=(100/17.5)*x       - we multiply both sides of the equation by x
1992=5.7142857142857*x       - we divide both sides of the equation by (5.7142857142857) to get x
1992/5.7142857142857=x
348.6=x
x=348.6

now we have:
17.5% of 1992=348.6
