2.14 is what percent of 10.2 - 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 10.2 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 100% equals 10.2, so we can write it down as 100%=10.2.
4. We know, that x% equals 2.14 of the output value, so we can write it down as x%=2.14.
5. Now we have two simple equations:
1) 100%=10.2
2) x%=2.14
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%=10.2/2.14
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.14 is what percent of 10.2

100%/x%=10.2/2.14
(100/x)*x=(10.2/2.14)*x       - we multiply both sides of the equation by x
100=4.7663551401869*x       - we divide both sides of the equation by (4.7663551401869) to get x
100/4.7663551401869=x
20.980392156863=x
x=20.980392156863

now we have:
2.14 is 20.980392156863% of 10.2
