What is 14.5 percent of 642.65 - 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 642.65 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 642.65 is 100%, so we can write it down as 642.65=100%.
4. We know, that x is 14.5% of the output value, so we can write it down as x=14.5%.
5. Now we have two simple equations:
1) 642.65=100%
2) x=14.5%
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:
642.65/x=100%/14.5%
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 14.5% of 642.65

642.65/x=100/14.5
(642.65/x)*x=(100/14.5)*x       - we multiply both sides of the equation by x
642.65=6.8965517241379*x       - we divide both sides of the equation by (6.8965517241379) to get x
642.65/6.8965517241379=x
93.18425=x
x=93.18425

now we have:
14.5% of 642.65=93.18425
