What is 55.5 percent of 490 - 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 490 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 490 is 100%, so we can write it down as 490=100%.
4. We know, that x is 55.5% of the output value, so we can write it down as x=55.5%.
5. Now we have two simple equations:
1) 490=100%
2) x=55.5%
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:
490/x=100%/55.5%
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 55.5% of 490

490/x=100/55.5
(490/x)*x=(100/55.5)*x       - we multiply both sides of the equation by x
490=1.8018018018018*x       - we divide both sides of the equation by (1.8018018018018) to get x
490/1.8018018018018=x
271.95=x
x=271.95

now we have:
55.5% of 490=271.95
