73 is what 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 100% equals 13, so we can write it down as 100%=13.
4. We know, that x% equals 73 of the output value, so we can write it down as x%=73.
5. Now we have two simple equations:
1) 100%=13
2) x%=73
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%=13/73
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 73 is what percent of 13

100%/x%=13/73
(100/x)*x=(13/73)*x       - we multiply both sides of the equation by x
100=0.17808219178082*x       - we divide both sides of the equation by (0.17808219178082) to get x
100/0.17808219178082=x
561.53846153846=x
x=561.53846153846

now we have:
73 is 561.53846153846% of 13
