159.69 is what percent of 900 - 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 900 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 900, so we can write it down as 100%=900.
4. We know, that x% equals 159.69 of the output value, so we can write it down as x%=159.69.
5. Now we have two simple equations:
1) 100%=900
2) x%=159.69
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%=900/159.69
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 159.69 is what percent of 900

100%/x%=900/159.69
(100/x)*x=(900/159.69)*x       - we multiply both sides of the equation by x
100=5.6359195942138*x       - we divide both sides of the equation by (5.6359195942138) to get x
100/5.6359195942138=x
17.743333333333=x
x=17.743333333333

now we have:
159.69 is 17.743333333333% of 900
