3.91 is what percent of 5.33 - 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 5.33 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 5.33, so we can write it down as 100%=5.33.
4. We know, that x% equals 3.91 of the output value, so we can write it down as x%=3.91.
5. Now we have two simple equations:
1) 100%=5.33
2) x%=3.91
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%=5.33/3.91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.91 is what percent of 5.33

100%/x%=5.33/3.91
(100/x)*x=(5.33/3.91)*x       - we multiply both sides of the equation by x
100=1.3631713554987*x       - we divide both sides of the equation by (1.3631713554987) to get x
100/1.3631713554987=x
73.358348968105=x
x=73.358348968105

now we have:
3.91 is 73.358348968105% of 5.33
