What is 13.8 percent of 358 - 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 358 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 358 is 100%, so we can write it down as 358=100%.
4. We know, that x is 13.8% of the output value, so we can write it down as x=13.8%.
5. Now we have two simple equations:
1) 358=100%
2) x=13.8%
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:
358/x=100%/13.8%
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 13.8% of 358

358/x=100/13.8
(358/x)*x=(100/13.8)*x       - we multiply both sides of the equation by x
358=7.2463768115942*x       - we divide both sides of the equation by (7.2463768115942) to get x
358/7.2463768115942=x
49.404=x
x=49.404

now we have:
13.8% of 358=49.404
