91 is what percent of 2340 - 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 2340 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 2340, so we can write it down as 100%=2340.
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%=2340
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%=2340/91
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 2340

100%/x%=2340/91
(100/x)*x=(2340/91)*x       - we multiply both sides of the equation by x
100=25.714285714286*x       - we divide both sides of the equation by (25.714285714286) to get x
100/25.714285714286=x
3.8888888888889=x
x=3.8888888888889

now we have:
91 is 3.8888888888889% of 2340
