What is 1998000 percent of 25 - 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 25 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 25 is 100%, so we can write it down as 25=100%.
4. We know, that x is 1998000% of the output value, so we can write it down as x=1998000%.
5. Now we have two simple equations:
1) 25=100%
2) x=1998000%
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:
25/x=100%/1998000%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 1998000% of 25

25/x=100/1998000
(25/x)*x=(100/1998000)*x       - we multiply both sides of the equation by x
25=5.005005005005E-5*x       - we divide both sides of the equation by (5.005005005005E-5) to get x
25/5.005005005005E-5=x
499500=x
x=499500

now we have:
1998000% of 25=499500
