30.8 is what percent of 1000 - 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 1000 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 1000, so we can write it down as 100%=1000.
4. We know, that x% equals 30.8 of the output value, so we can write it down as x%=30.8.
5. Now we have two simple equations:
1) 100%=1000
2) x%=30.8
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%=1000/30.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.8 is what percent of 1000

100%/x%=1000/30.8
(100/x)*x=(1000/30.8)*x       - we multiply both sides of the equation by x
100=32.467532467532*x       - we divide both sides of the equation by (32.467532467532) to get x
100/32.467532467532=x
3.08=x
x=3.08

now we have:
30.8 is 3.08% of 1000
