What is 20000000 percent of 450 - 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 450 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 450 is 100%, so we can write it down as 450=100%.
4. We know, that x is 20000000% of the output value, so we can write it down as x=20000000%.
5. Now we have two simple equations:
1) 450=100%
2) x=20000000%
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:
450/x=100%/20000000%
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 20000000% of 450

450/x=100/20000000
(450/x)*x=(100/20000000)*x       - we multiply both sides of the equation by x
450=5.0E-6*x       - we divide both sides of the equation by (5.0E-6) to get x
450/5.0E-6=x
90000000=x
x=90000000

now we have:
20000000% of 450=90000000
