77 is what percent of 163 - 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 163 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 163, so we can write it down as 100%=163.
4. We know, that x% equals 77 of the output value, so we can write it down as x%=77.
5. Now we have two simple equations:
1) 100%=163
2) x%=77
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%=163/77
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 77 is what percent of 163

100%/x%=163/77
(100/x)*x=(163/77)*x       - we multiply both sides of the equation by x
100=2.1168831168831*x       - we divide both sides of the equation by (2.1168831168831) to get x
100/2.1168831168831=x
47.239263803681=x
x=47.239263803681

now we have:
77 is 47.239263803681% of 163
