30 is what percent of 19895 - 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 19895 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 19895, so we can write it down as 100%=19895.
4. We know, that x% equals 30 of the output value, so we can write it down as x%=30.
5. Now we have two simple equations:
1) 100%=19895
2) x%=30
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%=19895/30
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30 is what percent of 19895

100%/x%=19895/30
(100/x)*x=(19895/30)*x       - we multiply both sides of the equation by x
100=663.16666666667*x       - we divide both sides of the equation by (663.16666666667) to get x
100/663.16666666667=x
0.15079165619502=x
x=0.15079165619502

now we have:
30 is 0.15079165619502% of 19895
