What is 4.3 percent of 7.2 - 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 7.2 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 7.2 is 100%, so we can write it down as 7.2=100%.
4. We know, that x is 4.3% of the output value, so we can write it down as x=4.3%.
5. Now we have two simple equations:
1) 7.2=100%
2) x=4.3%
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:
7.2/x=100%/4.3%
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 4.3% of 7.2

7.2/x=100/4.3
(7.2/x)*x=(100/4.3)*x       - we multiply both sides of the equation by x
7.2=23.255813953488*x       - we divide both sides of the equation by (23.255813953488) to get x
7.2/23.255813953488=x
0.3096=x
x=0.3096

now we have:
4.3% of 7.2=0.3096
