What is 28.5 percent of 498.45 - 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 498.45 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 498.45 is 100%, so we can write it down as 498.45=100%.
4. We know, that x is 28.5% of the output value, so we can write it down as x=28.5%.
5. Now we have two simple equations:
1) 498.45=100%
2) x=28.5%
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:
498.45/x=100%/28.5%
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 28.5% of 498.45

498.45/x=100/28.5
(498.45/x)*x=(100/28.5)*x       - we multiply both sides of the equation by x
498.45=3.5087719298246*x       - we divide both sides of the equation by (3.5087719298246) to get x
498.45/3.5087719298246=x
142.05825=x
x=142.05825

now we have:
28.5% of 498.45=142.05825
