What is 25.7 percent of 142.9 - 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 142.9 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 142.9 is 100%, so we can write it down as 142.9=100%.
4. We know, that x is 25.7% of the output value, so we can write it down as x=25.7%.
5. Now we have two simple equations:
1) 142.9=100%
2) x=25.7%
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:
142.9/x=100%/25.7%
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 25.7% of 142.9

142.9/x=100/25.7
(142.9/x)*x=(100/25.7)*x       - we multiply both sides of the equation by x
142.9=3.8910505836576*x       - we divide both sides of the equation by (3.8910505836576) to get x
142.9/3.8910505836576=x
36.7253=x
x=36.7253

now we have:
25.7% of 142.9=36.7253
