13.1 is what percent of 203 - 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 203 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 203, so we can write it down as 100%=203.
4. We know, that x% equals 13.1 of the output value, so we can write it down as x%=13.1.
5. Now we have two simple equations:
1) 100%=203
2) x%=13.1
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%=203/13.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.1 is what percent of 203

100%/x%=203/13.1
(100/x)*x=(203/13.1)*x       - we multiply both sides of the equation by x
100=15.496183206107*x       - we divide both sides of the equation by (15.496183206107) to get x
100/15.496183206107=x
6.4532019704433=x
x=6.4532019704433

now we have:
13.1 is 6.4532019704433% of 203
