278.81 is what percent of 955 - 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 955 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 955, so we can write it down as 100%=955.
4. We know, that x% equals 278.81 of the output value, so we can write it down as x%=278.81.
5. Now we have two simple equations:
1) 100%=955
2) x%=278.81
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%=955/278.81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 278.81 is what percent of 955

100%/x%=955/278.81
(100/x)*x=(955/278.81)*x       - we multiply both sides of the equation by x
100=3.4252716903985*x       - we divide both sides of the equation by (3.4252716903985) to get x
100/3.4252716903985=x
29.194764397906=x
x=29.194764397906

now we have:
278.81 is 29.194764397906% of 955
