3 is what percent of 18.68 - 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 18.68 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 18.68, so we can write it down as 100%=18.68.
4. We know, that x% equals 3 of the output value, so we can write it down as x%=3.
5. Now we have two simple equations:
1) 100%=18.68
2) x%=3
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%=18.68/3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3 is what percent of 18.68

100%/x%=18.68/3
(100/x)*x=(18.68/3)*x       - we multiply both sides of the equation by x
100=6.2266666666667*x       - we divide both sides of the equation by (6.2266666666667) to get x
100/6.2266666666667=x
16.059957173448=x
x=16.059957173448

now we have:
3 is 16.059957173448% of 18.68
