422.5 is what percent of 479 - 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 479 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 479, so we can write it down as 100%=479.
4. We know, that x% equals 422.5 of the output value, so we can write it down as x%=422.5.
5. Now we have two simple equations:
1) 100%=479
2) x%=422.5
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%=479/422.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 422.5 is what percent of 479

100%/x%=479/422.5
(100/x)*x=(479/422.5)*x       - we multiply both sides of the equation by x
100=1.1337278106509*x       - we divide both sides of the equation by (1.1337278106509) to get x
100/1.1337278106509=x
88.204592901879=x
x=88.204592901879

now we have:
422.5 is 88.204592901879% of 479
