77 is what percent of 801 - 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 801 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 801, so we can write it down as 100%=801.
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%=801
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%=801/77
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 801

100%/x%=801/77
(100/x)*x=(801/77)*x       - we multiply both sides of the equation by x
100=10.402597402597*x       - we divide both sides of the equation by (10.402597402597) to get x
100/10.402597402597=x
9.6129837702871=x
x=9.6129837702871

now we have:
77 is 9.6129837702871% of 801
