405.8 is what percent of 425 - 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 425 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 425, so we can write it down as 100%=425.
4. We know, that x% equals 405.8 of the output value, so we can write it down as x%=405.8.
5. Now we have two simple equations:
1) 100%=425
2) x%=405.8
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%=425/405.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 405.8 is what percent of 425

100%/x%=425/405.8
(100/x)*x=(425/405.8)*x       - we multiply both sides of the equation by x
100=1.0473139477575*x       - we divide both sides of the equation by (1.0473139477575) to get x
100/1.0473139477575=x
95.482352941176=x
x=95.482352941176

now we have:
405.8 is 95.482352941176% of 425
