6 is what percent of 77.4 - 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 77.4 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 77.4, so we can write it down as 100%=77.4.
4. We know, that x% equals 6 of the output value, so we can write it down as x%=6.
5. Now we have two simple equations:
1) 100%=77.4
2) x%=6
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%=77.4/6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6 is what percent of 77.4

100%/x%=77.4/6
(100/x)*x=(77.4/6)*x       - we multiply both sides of the equation by x
100=12.9*x       - we divide both sides of the equation by (12.9) to get x
100/12.9=x
7.7519379844961=x
x=7.7519379844961

now we have:
6 is 7.7519379844961% of 77.4
