89 is what percent of 1636 - 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 1636 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 1636, so we can write it down as 100%=1636.
4. We know, that x% equals 89 of the output value, so we can write it down as x%=89.
5. Now we have two simple equations:
1) 100%=1636
2) x%=89
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%=1636/89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 89 is what percent of 1636

100%/x%=1636/89
(100/x)*x=(1636/89)*x       - we multiply both sides of the equation by x
100=18.38202247191*x       - we divide both sides of the equation by (18.38202247191) to get x
100/18.38202247191=x
5.440097799511=x
x=5.440097799511

now we have:
89 is 5.440097799511% of 1636
