91 is what percent of 4700 - 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 4700 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 4700, so we can write it down as 100%=4700.
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%=4700
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%=4700/91
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 4700

100%/x%=4700/91
(100/x)*x=(4700/91)*x       - we multiply both sides of the equation by x
100=51.648351648352*x       - we divide both sides of the equation by (51.648351648352) to get x
100/51.648351648352=x
1.936170212766=x
x=1.936170212766

now we have:
91 is 1.936170212766% of 4700
