91 is what percent of 471 - 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 471 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 471, so we can write it down as 100%=471.
4. We know, that x% equals 91 of the output value, so we can write it down as x%=91.
5. Now we have two simple equations:
1) 100%=471
2) x%=91
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%=471/91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 91 is what percent of 471

100%/x%=471/91
(100/x)*x=(471/91)*x       - we multiply both sides of the equation by x
100=5.1758241758242*x       - we divide both sides of the equation by (5.1758241758242) to get x
100/5.1758241758242=x
19.32059447983=x
x=19.32059447983

now we have:
91 is 19.32059447983% of 471
