What is 61 percent of 20.77 - 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 20.77 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 20.77 is 100%, so we can write it down as 20.77=100%.
4. We know, that x is 61% of the output value, so we can write it down as x=61%.
5. Now we have two simple equations:
1) 20.77=100%
2) x=61%
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:
20.77/x=100%/61%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 61% of 20.77

20.77/x=100/61
(20.77/x)*x=(100/61)*x       - we multiply both sides of the equation by x
20.77=1.6393442622951*x       - we divide both sides of the equation by (1.6393442622951) to get x
20.77/1.6393442622951=x
12.6697=x
x=12.6697

now we have:
61% of 20.77=12.6697
