What is 12.93 percent of 172.4 - 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 172.4 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 172.4 is 100%, so we can write it down as 172.4=100%.
4. We know, that x is 12.93% of the output value, so we can write it down as x=12.93%.
5. Now we have two simple equations:
1) 172.4=100%
2) x=12.93%
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:
172.4/x=100%/12.93%
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 12.93% of 172.4

172.4/x=100/12.93
(172.4/x)*x=(100/12.93)*x       - we multiply both sides of the equation by x
172.4=7.7339520494973*x       - we divide both sides of the equation by (7.7339520494973) to get x
172.4/7.7339520494973=x
22.29132=x
x=22.29132

now we have:
12.93% of 172.4=22.29132
