13 is what percent of 730 - 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 730 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 730, so we can write it down as 100%=730.
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%=730
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%=730/13
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 730

100%/x%=730/13
(100/x)*x=(730/13)*x       - we multiply both sides of the equation by x
100=56.153846153846*x       - we divide both sides of the equation by (56.153846153846) to get x
100/56.153846153846=x
1.7808219178082=x
x=1.7808219178082

now we have:
13 is 1.7808219178082% of 730
