27 is what percent of 765 - 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 765 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 765, so we can write it down as 100%=765.
4. We know, that x% equals 27 of the output value, so we can write it down as x%=27.
5. Now we have two simple equations:
1) 100%=765
2) x%=27
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%=765/27
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27 is what percent of 765

100%/x%=765/27
(100/x)*x=(765/27)*x       - we multiply both sides of the equation by x
100=28.333333333333*x       - we divide both sides of the equation by (28.333333333333) to get x
100/28.333333333333=x
3.5294117647059=x
x=3.5294117647059

now we have:
27 is 3.5294117647059% of 765
