0.25 is what percent of 5500000 - 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 5500000 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 5500000, so we can write it down as 100%=5500000.
4. We know, that x% equals 0.25 of the output value, so we can write it down as x%=0.25.
5. Now we have two simple equations:
1) 100%=5500000
2) x%=0.25
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%=5500000/0.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.25 is what percent of 5500000

100%/x%=5500000/0.25
(100/x)*x=(5500000/0.25)*x       - we multiply both sides of the equation by x
100=22000000*x       - we divide both sides of the equation by (22000000) to get x
100/22000000=x
4.5454545454545E-6=x
x=4.5454545454545E-6

now we have:
0.25 is 4.5454545454545E-6% of 5500000
