What is 81.25 percent of 145.42 - 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 145.42 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 145.42 is 100%, so we can write it down as 145.42=100%.
4. We know, that x is 81.25% of the output value, so we can write it down as x=81.25%.
5. Now we have two simple equations:
1) 145.42=100%
2) x=81.25%
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:
145.42/x=100%/81.25%
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 81.25% of 145.42

145.42/x=100/81.25
(145.42/x)*x=(100/81.25)*x       - we multiply both sides of the equation by x
145.42=1.2307692307692*x       - we divide both sides of the equation by (1.2307692307692) to get x
145.42/1.2307692307692=x
118.15375=x
x=118.15375

now we have:
81.25% of 145.42=118.15375
