What is 59 percent of 21.138 - 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 21.138 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 21.138 is 100%, so we can write it down as 21.138=100%.
4. We know, that x is 59% of the output value, so we can write it down as x=59%.
5. Now we have two simple equations:
1) 21.138=100%
2) x=59%
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:
21.138/x=100%/59%
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 59% of 21.138

21.138/x=100/59
(21.138/x)*x=(100/59)*x       - we multiply both sides of the equation by x
21.138=1.6949152542373*x       - we divide both sides of the equation by (1.6949152542373) to get x
21.138/1.6949152542373=x
12.47142=x
x=12.47142

now we have:
59% of 21.138=12.47142
