78.8 is what percent of 278.1 - 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 278.1 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 278.1, so we can write it down as 100%=278.1.
4. We know, that x% equals 78.8 of the output value, so we can write it down as x%=78.8.
5. Now we have two simple equations:
1) 100%=278.1
2) x%=78.8
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%=278.1/78.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 78.8 is what percent of 278.1

100%/x%=278.1/78.8
(100/x)*x=(278.1/78.8)*x       - we multiply both sides of the equation by x
100=3.5291878172589*x       - we divide both sides of the equation by (3.5291878172589) to get x
100/3.5291878172589=x
28.335131247753=x
x=28.335131247753

now we have:
78.8 is 28.335131247753% of 278.1
