25 is what percent of 2778 - 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 2778 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 2778, so we can write it down as 100%=2778.
4. We know, that x% equals 25 of the output value, so we can write it down as x%=25.
5. Now we have two simple equations:
1) 100%=2778
2) x%=25
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%=2778/25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25 is what percent of 2778

100%/x%=2778/25
(100/x)*x=(2778/25)*x       - we multiply both sides of the equation by x
100=111.12*x       - we divide both sides of the equation by (111.12) to get x
100/111.12=x
0.89992800575954=x
x=0.89992800575954

now we have:
25 is 0.89992800575954% of 2778
