What is 1.33 percent of 639.097 - 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 639.097 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 639.097 is 100%, so we can write it down as 639.097=100%.
4. We know, that x is 1.33% of the output value, so we can write it down as x=1.33%.
5. Now we have two simple equations:
1) 639.097=100%
2) x=1.33%
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:
639.097/x=100%/1.33%
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 1.33% of 639.097

639.097/x=100/1.33
(639.097/x)*x=(100/1.33)*x       - we multiply both sides of the equation by x
639.097=75.187969924812*x       - we divide both sides of the equation by (75.187969924812) to get x
639.097/75.187969924812=x
8.4999901=x
x=8.4999901

now we have:
