7.71 is what percent of 28.77 - 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 28.77 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 28.77, so we can write it down as 100%=28.77.
4. We know, that x% equals 7.71 of the output value, so we can write it down as x%=7.71.
5. Now we have two simple equations:
1) 100%=28.77
2) x%=7.71
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%=28.77/7.71
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.71 is what percent of 28.77

100%/x%=28.77/7.71
(100/x)*x=(28.77/7.71)*x       - we multiply both sides of the equation by x
100=3.7315175097276*x       - we divide both sides of the equation by (3.7315175097276) to get x
100/3.7315175097276=x
26.798748696559=x
x=26.798748696559

now we have:
7.71 is 26.798748696559% of 28.77
