71.2 is what percent of 278.8 - 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 278.8 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 278.8, so we can write it down as 100%=278.8.
4. We know, that x% equals 71.2 of the output value, so we can write it down as x%=71.2.
5. Now we have two simple equations:
1) 100%=278.8
2) x%=71.2
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%=278.8/71.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 71.2 is what percent of 278.8

100%/x%=278.8/71.2
(100/x)*x=(278.8/71.2)*x       - we multiply both sides of the equation by x
100=3.9157303370787*x       - we divide both sides of the equation by (3.9157303370787) to get x
100/3.9157303370787=x
25.538020086083=x
x=25.538020086083

now we have:
71.2 is 25.538020086083% of 278.8
