What is 124.5 percent of 10.5 - 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 10.5 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 10.5 is 100%, so we can write it down as 10.5=100%.
4. We know, that x is 124.5% of the output value, so we can write it down as x=124.5%.
5. Now we have two simple equations:
1) 10.5=100%
2) x=124.5%
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:
10.5/x=100%/124.5%
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 124.5% of 10.5

10.5/x=100/124.5
(10.5/x)*x=(100/124.5)*x       - we multiply both sides of the equation by x
10.5=0.80321285140562*x       - we divide both sides of the equation by (0.80321285140562) to get x
10.5/0.80321285140562=x
13.0725=x
x=13.0725

now we have:
124.5% of 10.5=13.0725
