13 is what percent of 214 - 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 214 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 214, so we can write it down as 100%=214.
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%=214
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%=214/13
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 214

100%/x%=214/13
(100/x)*x=(214/13)*x       - we multiply both sides of the equation by x
100=16.4615384615*x       - we divide both sides of the equation by (16.4615384615) to get x
100/16.4615384615=x
6.07476635514=x
x=6.07476635514

now we have:
13 is 6.07476635514% of 214
