27 is what percent of 3845 - 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 3845 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 3845, so we can write it down as 100%=3845.
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%=3845
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%=3845/27
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 3845

100%/x%=3845/27
(100/x)*x=(3845/27)*x       - we multiply both sides of the equation by x
100=142.40740740741*x       - we divide both sides of the equation by (142.40740740741) to get x
100/142.40740740741=x
0.70221066319896=x
x=0.70221066319896

now we have:
27 is 0.70221066319896% of 3845
