3.98 is what percent of 18.02 - 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 18.02 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 100% equals 18.02, so we can write it down as 100%=18.02.
4. We know, that x% equals 3.98 of the output value, so we can write it down as x%=3.98.
5. Now we have two simple equations:
1) 100%=18.02
2) x%=3.98
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:
100%/x%=18.02/3.98
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.98 is what percent of 18.02

100%/x%=18.02/3.98
(100/x)*x=(18.02/3.98)*x       - we multiply both sides of the equation by x
100=4.5276381909548*x       - we divide both sides of the equation by (4.5276381909548) to get x
100/4.5276381909548=x
22.086570477248=x
x=22.086570477248

now we have:
3.98 is 22.086570477248% of 18.02
