6.4 is what percent of 3000 - 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 3000 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 3000, so we can write it down as 100%=3000.
4. We know, that x% equals 6.4 of the output value, so we can write it down as x%=6.4.
5. Now we have two simple equations:
1) 100%=3000
2) x%=6.4
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%=3000/6.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.4 is what percent of 3000

100%/x%=3000/6.4
(100/x)*x=(3000/6.4)*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:
6.4 is 0.21333333333333% of 3000
