What is 13.4 percent of 3800 - 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 3800 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 3800 is 100%, so we can write it down as 3800=100%.
4. We know, that x is 13.4% of the output value, so we can write it down as x=13.4%.
5. Now we have two simple equations:
1) 3800=100%
2) x=13.4%
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:
3800/x=100%/13.4%
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 13.4% of 3800

3800/x=100/13.4
(3800/x)*x=(100/13.4)*x       - we multiply both sides of the equation by x
3800=7.4626865671642*x       - we divide both sides of the equation by (7.4626865671642) to get x
3800/7.4626865671642=x
509.2=x
x=509.2

now we have:
13.4% of 3800=509.2
