What is 84.5 percent of 215 - 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 215 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 215 is 100%, so we can write it down as 215=100%.
4. We know, that x is 84.5% of the output value, so we can write it down as x=84.5%.
5. Now we have two simple equations:
1) 215=100%
2) x=84.5%
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:
215/x=100%/84.5%
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 84.5% of 215

215/x=100/84.5
(215/x)*x=(100/84.5)*x       - we multiply both sides of the equation by x
215=1.1834319526627*x       - we divide both sides of the equation by (1.1834319526627) to get x
215/1.1834319526627=x
181.675=x
x=181.675

now we have:
84.5% of 215=181.675
