127.5 is what percent of 19.125 - 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 19.125 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 19.125, so we can write it down as 100%=19.125.
4. We know, that x% equals 127.5 of the output value, so we can write it down as x%=127.5.
5. Now we have two simple equations:
1) 100%=19.125
2) x%=127.5
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%=19.125/127.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 127.5 is what percent of 19.125

100%/x%=19.125/127.5
(100/x)*x=(19.125/127.5)*x       - we multiply both sides of the equation by x
100=0.15*x       - we divide both sides of the equation by (0.15) to get x
100/0.15=x
666.66666666667=x
x=666.66666666667

now we have:
127.5 is 666.66666666667% of 19.125
