What is 20 percent of 242.59 - 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 242.59 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 242.59 is 100%, so we can write it down as 242.59=100%.
4. We know, that x is 20% of the output value, so we can write it down as x=20%.
5. Now we have two simple equations:
1) 242.59=100%
2) x=20%
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:
242.59/x=100%/20%
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 20% of 242.59

242.59/x=100/20
(242.59/x)*x=(100/20)*x       - we multiply both sides of the equation by x
242.59=5*x       - we divide both sides of the equation by (5) to get x
242.59/5=x
48.518=x
x=48.518

now we have:
20% of 242.59=48.518
