6.54 is what percent of 7.7 - 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 7.7 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 7.7, so we can write it down as 100%=7.7.
4. We know, that x% equals 6.54 of the output value, so we can write it down as x%=6.54.
5. Now we have two simple equations:
1) 100%=7.7
2) x%=6.54
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%=7.7/6.54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.54 is what percent of 7.7

100%/x%=7.7/6.54
(100/x)*x=(7.7/6.54)*x       - we multiply both sides of the equation by x
100=1.177370030581*x       - we divide both sides of the equation by (1.177370030581) to get x
100/1.177370030581=x
84.935064935065=x
x=84.935064935065

now we have:
6.54 is 84.935064935065% of 7.7
