What is 61.42 percent of 20 - 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 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 is 100%, so we can write it down as 20=100%.
4. We know, that x is 61.42% of the output value, so we can write it down as x=61.42%.
5. Now we have two simple equations:
1) 20=100%
2) x=61.42%
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/x=100%/61.42%
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 61.42% of 20

20/x=100/61.42
(20/x)*x=(100/61.42)*x       - we multiply both sides of the equation by x
20=1.6281341582546*x       - we divide both sides of the equation by (1.6281341582546) to get x
20/1.6281341582546=x
12.284=x
x=12.284

now we have:
61.42% of 20=12.284
