278.6 is what percent of 676.6 - 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 676.6 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 676.6, so we can write it down as 100%=676.6.
4. We know, that x% equals 278.6 of the output value, so we can write it down as x%=278.6.
5. Now we have two simple equations:
1) 100%=676.6
2) x%=278.6
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%=676.6/278.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 278.6 is what percent of 676.6

100%/x%=676.6/278.6
(100/x)*x=(676.6/278.6)*x       - we multiply both sides of the equation by x
100=2.4285714285714*x       - we divide both sides of the equation by (2.4285714285714) to get x
100/2.4285714285714=x
41.176470588235=x
x=41.176470588235

now we have:
278.6 is 41.176470588235% of 676.6
