What is 13.2 percent of 145 - 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 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 is 100%, so we can write it down as 145=100%.
4. We know, that x is 13.2% of the output value, so we can write it down as x=13.2%.
5. Now we have two simple equations:
1) 145=100%
2) x=13.2%
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/x=100%/13.2%
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 13.2% of 145

145/x=100/13.2
(145/x)*x=(100/13.2)*x       - we multiply both sides of the equation by x
145=7.5757575757576*x       - we divide both sides of the equation by (7.5757575757576) to get x
145/7.5757575757576=x
19.14=x
x=19.14

now we have:
13.2% of 145=19.14
