77 is what percent of 2443 - 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 2443 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 2443, so we can write it down as 100%=2443.
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%=2443
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%=2443/77
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 2443

100%/x%=2443/77
(100/x)*x=(2443/77)*x       - we multiply both sides of the equation by x
100=31.727272727273*x       - we divide both sides of the equation by (31.727272727273) to get x
100/31.727272727273=x
3.1518624641834=x
x=3.1518624641834

now we have:
77 is 3.1518624641834% of 2443
