13.49 is what percent of 619.5 - 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 619.5 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 619.5, so we can write it down as 100%=619.5.
4. We know, that x% equals 13.49 of the output value, so we can write it down as x%=13.49.
5. Now we have two simple equations:
1) 100%=619.5
2) x%=13.49
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%=619.5/13.49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.49 is what percent of 619.5

100%/x%=619.5/13.49
(100/x)*x=(619.5/13.49)*x       - we multiply both sides of the equation by x
100=45.92290585619*x       - we divide both sides of the equation by (45.92290585619) to get x
100/45.92290585619=x
2.1775625504439=x
x=2.1775625504439

now we have:
13.49 is 2.1775625504439% of 619.5
