17 is what percent of 989 - 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 989 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 989, so we can write it down as 100%=989.
4. We know, that x% equals 17 of the output value, so we can write it down as x%=17.
5. Now we have two simple equations:
1) 100%=989
2) x%=17
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%=989/17
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17 is what percent of 989

100%/x%=989/17
(100/x)*x=(989/17)*x       - we multiply both sides of the equation by x
100=58.176470588235*x       - we divide both sides of the equation by (58.176470588235) to get x
100/58.176470588235=x
1.7189079878665=x
x=1.7189079878665

now we have:
17 is 1.7189079878665% of 989
