19 is what percent of 1283 - 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 1283 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 1283, so we can write it down as 100%=1283.
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%=1283
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%=1283/19
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 1283

100%/x%=1283/19
(100/x)*x=(1283/19)*x       - we multiply both sides of the equation by x
100=67.526315789474*x       - we divide both sides of the equation by (67.526315789474) to get x
100/67.526315789474=x
1.4809041309431=x
x=1.4809041309431

now we have:
19 is 1.4809041309431% of 1283
