328.5 is what percent of 643.323 - 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 643.323 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 643.323, so we can write it down as 100%=643.323.
4. We know, that x% equals 328.5 of the output value, so we can write it down as x%=328.5.
5. Now we have two simple equations:
1) 100%=643.323
2) x%=328.5
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%=643.323/328.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 328.5 is what percent of 643.323

100%/x%=643.323/328.5
(100/x)*x=(643.323/328.5)*x       - we multiply both sides of the equation by x
100=1.9583652968037*x       - we divide both sides of the equation by (1.9583652968037) to get x
100/1.9583652968037=x
51.062996348646=x
x=51.062996348646

now we have:
