77 is what percent of 1394 - 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 1394 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 1394, so we can write it down as 100%=1394.
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%=1394
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%=1394/77
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 1394

100%/x%=1394/77
(100/x)*x=(1394/77)*x       - we multiply both sides of the equation by x
100=18.103896103896*x       - we divide both sides of the equation by (18.103896103896) to get x
100/18.103896103896=x
5.5236728837877=x
x=5.5236728837877

now we have:
77 is 5.5236728837877% of 1394
