19 is what percent of 10300 - 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 10300 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 10300, so we can write it down as 100%=10300.
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%=10300
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%=10300/19
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 10300

100%/x%=10300/19
(100/x)*x=(10300/19)*x       - we multiply both sides of the equation by x
100=542.10526315789*x       - we divide both sides of the equation by (542.10526315789) to get x
100/542.10526315789=x
0.18446601941748=x
x=0.18446601941748

now we have:
19 is 0.18446601941748% of 10300
