49.68 is what percent of 69 - 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 69 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 69, so we can write it down as 100%=69.
4. We know, that x% equals 49.68 of the output value, so we can write it down as x%=49.68.
5. Now we have two simple equations:
1) 100%=69
2) x%=49.68
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%=69/49.68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 49.68 is what percent of 69

100%/x%=69/49.68
(100/x)*x=(69/49.68)*x       - we multiply both sides of the equation by x
100=1.3888888888889*x       - we divide both sides of the equation by (1.3888888888889) to get x
100/1.3888888888889=x
72=x
x=72

now we have:
49.68 is 72% of 69
