77 is what percent of 1248 - 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 1248 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 1248, so we can write it down as 100%=1248.
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%=1248
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%=1248/77
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 1248

100%/x%=1248/77
(100/x)*x=(1248/77)*x       - we multiply both sides of the equation by x
100=16.207792207792*x       - we divide both sides of the equation by (16.207792207792) to get x
100/16.207792207792=x
6.1698717948718=x
x=6.1698717948718

now we have:
77 is 6.1698717948718% of 1248
