What is 12.24 percent of 428 - 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 428 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 428 is 100%, so we can write it down as 428=100%.
4. We know, that x is 12.24% of the output value, so we can write it down as x=12.24%.
5. Now we have two simple equations:
1) 428=100%
2) x=12.24%
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:
428/x=100%/12.24%
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 12.24% of 428

428/x=100/12.24
(428/x)*x=(100/12.24)*x       - we multiply both sides of the equation by x
428=8.1699346405229*x       - we divide both sides of the equation by (8.1699346405229) to get x
428/8.1699346405229=x
52.3872=x
x=52.3872

now we have:
12.24% of 428=52.3872
