51 is what percent of 61.77 - 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 61.77 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 61.77, so we can write it down as 100%=61.77.
4. We know, that x% equals 51 of the output value, so we can write it down as x%=51.
5. Now we have two simple equations:
1) 100%=61.77
2) x%=51
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%=61.77/51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51 is what percent of 61.77

100%/x%=61.77/51
(100/x)*x=(61.77/51)*x       - we multiply both sides of the equation by x
100=1.2111764705882*x       - we divide both sides of the equation by (1.2111764705882) to get x
100/1.2111764705882=x
82.564351627003=x
x=82.564351627003

now we have:
51 is 82.564351627003% of 61.77
