1.86 is what percent of 2.57 - 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 2.57 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 2.57, so we can write it down as 100%=2.57.
4. We know, that x% equals 1.86 of the output value, so we can write it down as x%=1.86.
5. Now we have two simple equations:
1) 100%=2.57
2) x%=1.86
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%=2.57/1.86
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.86 is what percent of 2.57

100%/x%=2.57/1.86
(100/x)*x=(2.57/1.86)*x       - we multiply both sides of the equation by x
100=1.3817204301075*x       - we divide both sides of the equation by (1.3817204301075) to get x
100/1.3817204301075=x
72.373540856031=x
x=72.373540856031

now we have:
1.86 is 72.373540856031% of 2.57
