What is 17.5 percent of 20.2 - 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 20.2 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 20.2 is 100%, so we can write it down as 20.2=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) 20.2=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:
20.2/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 20.2

20.2/x=100/17.5
(20.2/x)*x=(100/17.5)*x       - we multiply both sides of the equation by x
20.2=5.7142857142857*x       - we divide both sides of the equation by (5.7142857142857) to get x
20.2/5.7142857142857=x
3.535=x
x=3.535

now we have:
17.5% of 20.2=3.535
