What is 43 percent of 5.09 - 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 5.09 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 5.09 is 100%, so we can write it down as 5.09=100%.
4. We know, that x is 43% of the output value, so we can write it down as x=43%.
5. Now we have two simple equations:
1) 5.09=100%
2) x=43%
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:
5.09/x=100%/43%
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 43% of 5.09

5.09/x=100/43
(5.09/x)*x=(100/43)*x       - we multiply both sides of the equation by x
5.09=2.3255813953488*x       - we divide both sides of the equation by (2.3255813953488) to get x
5.09/2.3255813953488=x
2.1887=x
x=2.1887

now we have:
43% of 5.09=2.1887
