What is 72.09 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 43 is 100%, so we can write it down as 43=100%.
4. We know, that x is 72.09% of the output value, so we can write it down as x=72.09%.
5. Now we have two simple equations:
1) 43=100%
2) x=72.09%
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:
43/x=100%/72.09%
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 72.09% of 43

43/x=100/72.09
(43/x)*x=(100/72.09)*x       - we multiply both sides of the equation by x
43=1.3871549452074*x       - we divide both sides of the equation by (1.3871549452074) to get x
43/1.3871549452074=x
30.9987=x
x=30.9987

now we have:
72.09% of 43=30.9987
