What is 5.3 percent of 12400 - 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 12400 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 12400 is 100%, so we can write it down as 12400=100%.
4. We know, that x is 5.3% of the output value, so we can write it down as x=5.3%.
5. Now we have two simple equations:
1) 12400=100%
2) x=5.3%
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:
12400/x=100%/5.3%
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 5.3% of 12400

12400/x=100/5.3
(12400/x)*x=(100/5.3)*x       - we multiply both sides of the equation by x
12400=18.867924528302*x       - we divide both sides of the equation by (18.867924528302) to get x
12400/18.867924528302=x
657.2=x
x=657.2

now we have:
5.3% of 12400=657.2
