7.79 is what percent of 19 - 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 19 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 19, so we can write it down as 100%=19.
4. We know, that x% equals 7.79 of the output value, so we can write it down as x%=7.79.
5. Now we have two simple equations:
1) 100%=19
2) x%=7.79
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%=19/7.79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.79 is what percent of 19

100%/x%=19/7.79
(100/x)*x=(19/7.79)*x       - we multiply both sides of the equation by x
100=2.4390243902439*x       - we divide both sides of the equation by (2.4390243902439) to get x
100/2.4390243902439=x
41=x
x=41

now we have:
7.79 is 41% of 19
