What is 39.1 percent of 230 - 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 230 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 230 is 100%, so we can write it down as 230=100%.
4. We know, that x is 39.1% of the output value, so we can write it down as x=39.1%.
5. Now we have two simple equations:
1) 230=100%
2) x=39.1%
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:
230/x=100%/39.1%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 39.1% of 230

230/x=100/39.1
(230/x)*x=(100/39.1)*x       - we multiply both sides of the equation by x
230=2.5575447570332*x       - we divide both sides of the equation by (2.5575447570332) to get x
230/2.5575447570332=x
89.93=x
x=89.93

now we have:
39.1% of 230=89.93
