7.81 is what 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 100% equals 112, so we can write it down as 100%=112.
4. We know, that x% equals 7.81 of the output value, so we can write it down as x%=7.81.
5. Now we have two simple equations:
1) 100%=112
2) x%=7.81
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:
100%/x%=112/7.81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.81 is what percent of 112

100%/x%=112/7.81
(100/x)*x=(112/7.81)*x       - we multiply both sides of the equation by x
100=14.340588988476*x       - we divide both sides of the equation by (14.340588988476) to get x
100/14.340588988476=x
6.9732142857143=x
x=6.9732142857143

now we have:
7.81 is 6.9732142857143% of 112
