What is 215 percent of 8 - 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 8 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 8 is 100%, so we can write it down as 8=100%.
4. We know, that x is 215% of the output value, so we can write it down as x=215%.
5. Now we have two simple equations:
1) 8=100%
2) x=215%
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:
8/x=100%/215%
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 215% of 8

8/x=100/215
(8/x)*x=(100/215)*x       - we multiply both sides of the equation by x
8=0.46511627906977*x       - we divide both sides of the equation by (0.46511627906977) to get x
8/0.46511627906977=x
17.2=x
x=17.2

now we have:
215% of 8=17.2
