10.5 is what percent of 132.1 - 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 132.1 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 100% equals 132.1, so we can write it down as 100%=132.1.
4. We know, that x% equals 10.5 of the output value, so we can write it down as x%=10.5.
5. Now we have two simple equations:
1) 100%=132.1
2) x%=10.5
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:
100%/x%=132.1/10.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10.5 is what percent of 132.1

100%/x%=132.1/10.5
(100/x)*x=(132.1/10.5)*x       - we multiply both sides of the equation by x
100=12.580952380952*x       - we divide both sides of the equation by (12.580952380952) to get x
100/12.580952380952=x
7.9485238455715=x
x=7.9485238455715

now we have:
10.5 is 7.9485238455715% of 132.1
