63 is what percent of 83 - 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 83 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 83, so we can write it down as 100%=83.
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%=83
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%=83/63
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 83

100%/x%=83/63
(100/x)*x=(83/63)*x       - we multiply both sides of the equation by x
100=1.31746031746*x       - we divide both sides of the equation by (1.31746031746) to get x
100/1.31746031746=x
75.9036144578=x
x=75.9036144578

now we have:
63 is 75.9036144578% of 83
