99 is what percent of 887 - 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 887 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 887, so we can write it down as 100%=887.
4. We know, that x% equals 99 of the output value, so we can write it down as x%=99.
5. Now we have two simple equations:
1) 100%=887
2) x%=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%=887/99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 99 is what percent of 887

100%/x%=887/99
(100/x)*x=(887/99)*x       - we multiply both sides of the equation by x
100=8.959595959596*x       - we divide both sides of the equation by (8.959595959596) to get x
100/8.959595959596=x
11.161217587373=x
x=11.161217587373

now we have:
99 is 11.161217587373% of 887
