1.28 is what percent of 750 - 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 750 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 750, so we can write it down as 100%=750.
4. We know, that x% equals 1.28 of the output value, so we can write it down as x%=1.28.
5. Now we have two simple equations:
1) 100%=750
2) x%=1.28
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%=750/1.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.28 is what percent of 750

100%/x%=750/1.28
(100/x)*x=(750/1.28)*x       - we multiply both sides of the equation by x
100=585.9375*x       - we divide both sides of the equation by (585.9375) to get x
100/585.9375=x
0.17066666666667=x
x=0.17066666666667

now we have:
1.28 is 0.17066666666667% of 750
