89.99 is what percent of 110 - 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 110 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 110, so we can write it down as 100%=110.
4. We know, that x% equals 89.99 of the output value, so we can write it down as x%=89.99.
5. Now we have two simple equations:
1) 100%=110
2) x%=89.99
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%=110/89.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 89.99 is what percent of 110

100%/x%=110/89.99
(100/x)*x=(110/89.99)*x       - we multiply both sides of the equation by x
100=1.2223580397822*x       - we divide both sides of the equation by (1.2223580397822) to get x
100/1.2223580397822=x
81.809090909091=x
x=81.809090909091

now we have:
89.99 is 81.809090909091% of 110
