What is 55 percent of 137.5 - 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 137.5 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 137.5 is 100%, so we can write it down as 137.5=100%.
4. We know, that x is 55% of the output value, so we can write it down as x=55%.
5. Now we have two simple equations:
1) 137.5=100%
2) x=55%
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:
137.5/x=100%/55%
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 55% of 137.5

137.5/x=100/55
(137.5/x)*x=(100/55)*x       - we multiply both sides of the equation by x
137.5=1.81818181818*x       - we divide both sides of the equation by (1.81818181818) to get x
137.5/1.81818181818=x
75.625=x
x=75.625

now we have:
55% of 137.5=75.625
