What is 20.2 percent of 90.01 - 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 90.01 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 90.01 is 100%, so we can write it down as 90.01=100%.
4. We know, that x is 20.2% of the output value, so we can write it down as x=20.2%.
5. Now we have two simple equations:
1) 90.01=100%
2) x=20.2%
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:
90.01/x=100%/20.2%
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 20.2% of 90.01

90.01/x=100/20.2
(90.01/x)*x=(100/20.2)*x       - we multiply both sides of the equation by x
90.01=4.950495049505*x       - we divide both sides of the equation by (4.950495049505) to get x
90.01/4.950495049505=x
18.18202=x
x=18.18202

now we have:
20.2% of 90.01=18.18202
