What is 13.4 percent of 13 - 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 13 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 13 is 100%, so we can write it down as 13=100%.
4. We know, that x is 13.4% of the output value, so we can write it down as x=13.4%.
5. Now we have two simple equations:
1) 13=100%
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:
13/x=100%/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 what is 13.4% of 13

13/x=100/13.4
(13/x)*x=(100/13.4)*x       - we multiply both sides of the equation by x
13=7.4626865671642*x       - we divide both sides of the equation by (7.4626865671642) to get x
13/7.4626865671642=x
1.742=x
x=1.742

now we have:
13.4% of 13=1.742
