7 is what percent of 13.53 - 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 13.53 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 13.53, so we can write it down as 100%=13.53.
4. We know, that x% equals 7 of the output value, so we can write it down as x%=7.
5. Now we have two simple equations:
1) 100%=13.53
2) x%=7
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%=13.53/7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7 is what percent of 13.53

100%/x%=13.53/7
(100/x)*x=(13.53/7)*x       - we multiply both sides of the equation by x
100=1.9328571428571*x       - we divide both sides of the equation by (1.9328571428571) to get x
100/1.9328571428571=x
51.736881005174=x
x=51.736881005174

now we have:
7 is 51.736881005174% of 13.53
