1.72 is what percent of 30.4 - 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 30.4 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 30.4, so we can write it down as 100%=30.4.
4. We know, that x% equals 1.72 of the output value, so we can write it down as x%=1.72.
5. Now we have two simple equations:
1) 100%=30.4
2) x%=1.72
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%=30.4/1.72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.72 is what percent of 30.4

100%/x%=30.4/1.72
(100/x)*x=(30.4/1.72)*x       - we multiply both sides of the equation by x
100=17.674418604651*x       - we divide both sides of the equation by (17.674418604651) to get x
100/17.674418604651=x
5.6578947368421=x
x=5.6578947368421

now we have:
1.72 is 5.6578947368421% of 30.4
