What is 12.2 percent of 145.25 - 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 145.25 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 145.25 is 100%, so we can write it down as 145.25=100%.
4. We know, that x is 12.2% of the output value, so we can write it down as x=12.2%.
5. Now we have two simple equations:
1) 145.25=100%
2) x=12.2%
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:
145.25/x=100%/12.2%
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 12.2% of 145.25

145.25/x=100/12.2
(145.25/x)*x=(100/12.2)*x       - we multiply both sides of the equation by x
145.25=8.1967213114754*x       - we divide both sides of the equation by (8.1967213114754) to get x
145.25/8.1967213114754=x
17.7205=x
x=17.7205

now we have:
12.2% of 145.25=17.7205
