13.75 is what percent of 9 - 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 9 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 9, so we can write it down as 100%=9.
4. We know, that x% equals 13.75 of the output value, so we can write it down as x%=13.75.
5. Now we have two simple equations:
1) 100%=9
2) x%=13.75
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%=9/13.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.75 is what percent of 9

100%/x%=9/13.75
(100/x)*x=(9/13.75)*x       - we multiply both sides of the equation by x
100=0.65454545454545*x       - we divide both sides of the equation by (0.65454545454545) to get x
100/0.65454545454545=x
152.77777777778=x
x=152.77777777778

now we have:
13.75 is 152.77777777778% of 9
