8.6 is what percent of 300 - 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 300 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 100% equals 300, so we can write it down as 100%=300.
4. We know, that x% equals 8.6 of the output value, so we can write it down as x%=8.6.
5. Now we have two simple equations:
1) 100%=300
2) x%=8.6
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:
100%/x%=300/8.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.6 is what percent of 300

100%/x%=300/8.6
(100/x)*x=(300/8.6)*x       - we multiply both sides of the equation by x
100=34.883720930233*x       - we divide both sides of the equation by (34.883720930233) to get x
100/34.883720930233=x
2.8666666666667=x
x=2.8666666666667

now we have:
8.6 is 2.8666666666667% of 300
