271.51 is what percent of 869 - 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 869 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 869, so we can write it down as 100%=869.
4. We know, that x% equals 271.51 of the output value, so we can write it down as x%=271.51.
5. Now we have two simple equations:
1) 100%=869
2) x%=271.51
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%=869/271.51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 271.51 is what percent of 869

100%/x%=869/271.51
(100/x)*x=(869/271.51)*x       - we multiply both sides of the equation by x
100=3.2006187617399*x       - we divide both sides of the equation by (3.2006187617399) to get x
100/3.2006187617399=x
31.243958573072=x
x=31.243958573072

now we have:
271.51 is 31.243958573072% of 869
