35 is what percent of 641 - 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 641 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 641, so we can write it down as 100%=641.
4. We know, that x% equals 35 of the output value, so we can write it down as x%=35.
5. Now we have two simple equations:
1) 100%=641
2) x%=35
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%=641/35
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 35 is what percent of 641

100%/x%=641/35
(100/x)*x=(641/35)*x       - we multiply both sides of the equation by x
100=18.314285714286*x       - we divide both sides of the equation by (18.314285714286) to get x
100/18.314285714286=x
5.4602184087363=x
x=5.4602184087363

now we have:
35 is 5.4602184087363% of 641
