What is 39.45 percent of 550 - 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 550 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 550 is 100%, so we can write it down as 550=100%.
4. We know, that x is 39.45% of the output value, so we can write it down as x=39.45%.
5. Now we have two simple equations:
1) 550=100%
2) x=39.45%
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:
550/x=100%/39.45%
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 39.45% of 550

550/x=100/39.45
(550/x)*x=(100/39.45)*x       - we multiply both sides of the equation by x
550=2.5348542458809*x       - we divide both sides of the equation by (2.5348542458809) to get x
550/2.5348542458809=x
216.975=x
x=216.975

now we have:
39.45% of 550=216.975
