What is 81.5 percent of 112 - 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 112 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 112 is 100%, so we can write it down as 112=100%.
4. We know, that x is 81.5% of the output value, so we can write it down as x=81.5%.
5. Now we have two simple equations:
1) 112=100%
2) x=81.5%
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:
112/x=100%/81.5%
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 81.5% of 112

112/x=100/81.5
(112/x)*x=(100/81.5)*x       - we multiply both sides of the equation by x
112=1.2269938650307*x       - we divide both sides of the equation by (1.2269938650307) to get x
112/1.2269938650307=x
91.28=x
x=91.28

now we have:
81.5% of 112=91.28
