1.72 is what percent of 2.55 - 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 2.55 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 2.55, so we can write it down as 100%=2.55.
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%=2.55
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%=2.55/1.72
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 2.55

100%/x%=2.55/1.72
(100/x)*x=(2.55/1.72)*x       - we multiply both sides of the equation by x
100=1.4825581395349*x       - we divide both sides of the equation by (1.4825581395349) to get x
100/1.4825581395349=x
67.450980392157=x
x=67.450980392157

now we have:
1.72 is 67.450980392157% of 2.55
