13.4 is what percent of 165 - 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 165 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 165, so we can write it down as 100%=165.
4. We know, that x% equals 13.4 of the output value, so we can write it down as x%=13.4.
5. Now we have two simple equations:
1) 100%=165
2) x%=13.4
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%=165/13.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.4 is what percent of 165

100%/x%=165/13.4
(100/x)*x=(165/13.4)*x       - we multiply both sides of the equation by x
100=12.313432835821*x       - we divide both sides of the equation by (12.313432835821) to get x
100/12.313432835821=x
8.1212121212121=x
x=8.1212121212121

now we have:
13.4 is 8.1212121212121% of 165
