394.5 is what percent of 492 - 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 492 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 100% equals 492, so we can write it down as 100%=492.
4. We know, that x% equals 394.5 of the output value, so we can write it down as x%=394.5.
5. Now we have two simple equations:
1) 100%=492
2) x%=394.5
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:
100%/x%=492/394.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 394.5 is what percent of 492

100%/x%=492/394.5
(100/x)*x=(492/394.5)*x       - we multiply both sides of the equation by x
100=1.2471482889734*x       - we divide both sides of the equation by (1.2471482889734) to get x
100/1.2471482889734=x
80.182926829268=x
x=80.182926829268

now we have:
394.5 is 80.182926829268% of 492
