17.72 is what percent of 5.8 - 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 5.8 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 5.8, so we can write it down as 100%=5.8.
4. We know, that x% equals 17.72 of the output value, so we can write it down as x%=17.72.
5. Now we have two simple equations:
1) 100%=5.8
2) x%=17.72
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%=5.8/17.72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.72 is what percent of 5.8

100%/x%=5.8/17.72
(100/x)*x=(5.8/17.72)*x       - we multiply both sides of the equation by x
100=0.32731376975169*x       - we divide both sides of the equation by (0.32731376975169) to get x
100/0.32731376975169=x
305.51724137931=x
x=305.51724137931

now we have:
17.72 is 305.51724137931% of 5.8
