What is 0.89 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 0.89% of the output value, so we can write it down as x=0.89%.
5. Now we have two simple equations:
1) 450=100%
2) x=0.89%
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:
450/x=100%/0.89%
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 0.89% of 450

450/x=100/0.89
(450/x)*x=(100/0.89)*x       - we multiply both sides of the equation by x
450=112.3595505618*x       - we divide both sides of the equation by (112.3595505618) to get x
450/112.3595505618=x
4.005=x
x=4.005

now we have:
0.89% of 450=4.005
