13 is what percent of 377 - 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 377 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 377, so we can write it down as 100%=377.
4. We know, that x% equals 13 of the output value, so we can write it down as x%=13.
5. Now we have two simple equations:
1) 100%=377
2) x%=13
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%=377/13
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13 is what percent of 377

100%/x%=377/13
(100/x)*x=(377/13)*x       - we multiply both sides of the equation by x
100=29*x       - we divide both sides of the equation by (29) to get x
100/29=x
3.448275862069=x
x=3.448275862069

now we have:
13 is 3.448275862069% of 377
