1.72 is what percent of 9.72 - 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 9.72 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 9.72, so we can write it down as 100%=9.72.
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%=9.72
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%=9.72/1.72
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 9.72

100%/x%=9.72/1.72
(100/x)*x=(9.72/1.72)*x       - we multiply both sides of the equation by x
100=5.6511627906977*x       - we divide both sides of the equation by (5.6511627906977) to get x
100/5.6511627906977=x
17.695473251029=x
x=17.695473251029

now we have:
1.72 is 17.695473251029% of 9.72
