1.72 is what percent of 64.5 - 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 64.5 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 64.5, so we can write it down as 100%=64.5.
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%=64.5
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%=64.5/1.72
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 64.5

100%/x%=64.5/1.72
(100/x)*x=(64.5/1.72)*x       - we multiply both sides of the equation by x
100=37.5*x       - we divide both sides of the equation by (37.5) to get x
100/37.5=x
2.6666666666667=x
x=2.6666666666667

now we have:
1.72 is 2.6666666666667% of 64.5
