3.5 is what percent of 18.89 - 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 18.89 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 18.89, so we can write it down as 100%=18.89.
4. We know, that x% equals 3.5 of the output value, so we can write it down as x%=3.5.
5. Now we have two simple equations:
1) 100%=18.89
2) x%=3.5
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%=18.89/3.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.5 is what percent of 18.89

100%/x%=18.89/3.5
(100/x)*x=(18.89/3.5)*x       - we multiply both sides of the equation by x
100=5.3971428571429*x       - we divide both sides of the equation by (5.3971428571429) to get x
100/5.3971428571429=x
18.52832186342=x
x=18.52832186342

now we have:
3.5 is 18.52832186342% of 18.89
