What is 25 percent of 137.59 - 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 137.59 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 137.59 is 100%, so we can write it down as 137.59=100%.
4. We know, that x is 25% of the output value, so we can write it down as x=25%.
5. Now we have two simple equations:
1) 137.59=100%
2) x=25%
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:
137.59/x=100%/25%
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% of 137.59

137.59/x=100/25
(137.59/x)*x=(100/25)*x       - we multiply both sides of the equation by x
137.59=4*x       - we divide both sides of the equation by (4) to get x
137.59/4=x
34.3975=x
x=34.3975

now we have:
25% of 137.59=34.3975
