What is 0.3365 percent of 645.8 - 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 645.8 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 645.8 is 100%, so we can write it down as 645.8=100%.
4. We know, that x is 0.3365% of the output value, so we can write it down as x=0.3365%.
5. Now we have two simple equations:
1) 645.8=100%
2) x=0.3365%
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:
645.8/x=100%/0.3365%
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 0.3365% of 645.8

645.8/x=100/0.3365
(645.8/x)*x=(100/0.3365)*x       - we multiply both sides of the equation by x
645.8=297.17682020802*x       - we divide both sides of the equation by (297.17682020802) to get x
645.8/297.17682020802=x
2.173117=x
x=2.173117

now we have:
0.3365% of 645.8=2.173117
