13.75 is what percent of 18.75 - 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 18.75 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 18.75, so we can write it down as 100%=18.75.
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%=18.75
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%=18.75/13.75
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 18.75

100%/x%=18.75/13.75
(100/x)*x=(18.75/13.75)*x       - we multiply both sides of the equation by x
100=1.3636363636364*x       - we divide both sides of the equation by (1.3636363636364) to get x
100/1.3636363636364=x
73.333333333333=x
x=73.333333333333

now we have:
13.75 is 73.333333333333% of 18.75
