19 is what percent of 227 - 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 227 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 227, so we can write it down as 100%=227.
4. We know, that x% equals 19 of the output value, so we can write it down as x%=19.
5. Now we have two simple equations:
1) 100%=227
2) x%=19
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%=227/19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19 is what percent of 227

100%/x%=227/19
(100/x)*x=(227/19)*x       - we multiply both sides of the equation by x
100=11.947368421053*x       - we divide both sides of the equation by (11.947368421053) to get x
100/11.947368421053=x
8.3700440528634=x
x=8.3700440528634

now we have:
19 is 8.3700440528634% of 227
