63 is what percent of 1605 - 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 1605 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 1605, so we can write it down as 100%=1605.
4. We know, that x% equals 63 of the output value, so we can write it down as x%=63.
5. Now we have two simple equations:
1) 100%=1605
2) x%=63
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%=1605/63
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 63 is what percent of 1605

100%/x%=1605/63
(100/x)*x=(1605/63)*x       - we multiply both sides of the equation by x
100=25.47619047619*x       - we divide both sides of the equation by (25.47619047619) to get x
100/25.47619047619=x
3.9252336448598=x
x=3.9252336448598

now we have:
63 is 3.9252336448598% of 1605
