5.81 is what percent of 43 - 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 43 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 43, so we can write it down as 100%=43.
4. We know, that x% equals 5.81 of the output value, so we can write it down as x%=5.81.
5. Now we have two simple equations:
1) 100%=43
2) x%=5.81
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%=43/5.81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.81 is what percent of 43

100%/x%=43/5.81
(100/x)*x=(43/5.81)*x       - we multiply both sides of the equation by x
100=7.4010327022375*x       - we divide both sides of the equation by (7.4010327022375) to get x
100/7.4010327022375=x
13.511627906977=x
x=13.511627906977

now we have:
5.81 is 13.511627906977% of 43
