What is 4.3 percent of 172 - 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 172 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 172 is 100%, so we can write it down as 172=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) 172=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:
172/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 172

172/x=100/4.3
(172/x)*x=(100/4.3)*x       - we multiply both sides of the equation by x
172=23.255813953488*x       - we divide both sides of the equation by (23.255813953488) to get x
172/23.255813953488=x
7.396=x
x=7.396

now we have:
4.3% of 172=7.396
