122.25 is what percent of 156.48 - 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 156.48 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 156.48, so we can write it down as 100%=156.48.
4. We know, that x% equals 122.25 of the output value, so we can write it down as x%=122.25.
5. Now we have two simple equations:
1) 100%=156.48
2) x%=122.25
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%=156.48/122.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 122.25 is what percent of 156.48

100%/x%=156.48/122.25
(100/x)*x=(156.48/122.25)*x       - we multiply both sides of the equation by x
100=1.28*x       - we divide both sides of the equation by (1.28) to get x
100/1.28=x
78.125=x
x=78.125

now we have:
122.25 is 78.125% of 156.48
