What is 3.6 percent of 649 - 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 649 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 649 is 100%, so we can write it down as 649=100%.
4. We know, that x is 3.6% of the output value, so we can write it down as x=3.6%.
5. Now we have two simple equations:
1) 649=100%
2) x=3.6%
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:
649/x=100%/3.6%
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 3.6% of 649

649/x=100/3.6
(649/x)*x=(100/3.6)*x       - we multiply both sides of the equation by x
649=27.777777777778*x       - we divide both sides of the equation by (27.777777777778) to get x
649/27.777777777778=x
23.364=x
x=23.364

now we have:
3.6% of 649=23.364
