111.99 is what percent of 139.99 - 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 139.99 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 139.99, so we can write it down as 100%=139.99.
4. We know, that x% equals 111.99 of the output value, so we can write it down as x%=111.99.
5. Now we have two simple equations:
1) 100%=139.99
2) x%=111.99
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%=139.99/111.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 111.99 is what percent of 139.99

100%/x%=139.99/111.99
(100/x)*x=(139.99/111.99)*x       - we multiply both sides of the equation by x
100=1.2500223234217*x       - we divide both sides of the equation by (1.2500223234217) to get x
100/1.2500223234217=x
79.998571326523=x
x=79.998571326523

now we have:
111.99 is 79.998571326523% of 139.99
