1.28 is what percent of 600 - 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 600 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 600, so we can write it down as 100%=600.
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%=600
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%=600/1.28
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 600

100%/x%=600/1.28
(100/x)*x=(600/1.28)*x       - we multiply both sides of the equation by x
100=468.75*x       - we divide both sides of the equation by (468.75) to get x
100/468.75=x
0.21333333333333=x
x=0.21333333333333

now we have:
1.28 is 0.21333333333333% of 600
