15.78 is what percent of 65 - 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 65 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 65, so we can write it down as 100%=65.
4. We know, that x% equals 15.78 of the output value, so we can write it down as x%=15.78.
5. Now we have two simple equations:
1) 100%=65
2) x%=15.78
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%=65/15.78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.78 is what percent of 65

100%/x%=65/15.78
(100/x)*x=(65/15.78)*x       - we multiply both sides of the equation by x
100=4.1191381495564*x       - we divide both sides of the equation by (4.1191381495564) to get x
100/4.1191381495564=x
24.276923076923=x
x=24.276923076923

now we have:
15.78 is 24.276923076923% of 65
