What is 89 percent of 450000 - 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 450000 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 450000 is 100%, so we can write it down as 450000=100%.
4. We know, that x is 89% of the output value, so we can write it down as x=89%.
5. Now we have two simple equations:
1) 450000=100%
2) x=89%
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:
450000/x=100%/89%
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 89% of 450000

450000/x=100/89
(450000/x)*x=(100/89)*x       - we multiply both sides of the equation by x
450000=1.123595505618*x       - we divide both sides of the equation by (1.123595505618) to get x
450000/1.123595505618=x
400500=x
x=400500

now we have:
89% of 450000=400500
