13 is what percent of 923 - 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 923 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 923, so we can write it down as 100%=923.
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%=923
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%=923/13
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 923

100%/x%=923/13
(100/x)*x=(923/13)*x       - we multiply both sides of the equation by x
100=71*x       - we divide both sides of the equation by (71) to get x
100/71=x
1.4084507042254=x
x=1.4084507042254

now we have:
13 is 1.4084507042254% of 923
