1.45 is what percent of 2.8 - 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 2.8 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 2.8, so we can write it down as 100%=2.8.
4. We know, that x% equals 1.45 of the output value, so we can write it down as x%=1.45.
5. Now we have two simple equations:
1) 100%=2.8
2) x%=1.45
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%=2.8/1.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.45 is what percent of 2.8

100%/x%=2.8/1.45
(100/x)*x=(2.8/1.45)*x       - we multiply both sides of the equation by x
100=1.9310344827586*x       - we divide both sides of the equation by (1.9310344827586) to get x
100/1.9310344827586=x
51.785714285714=x
x=51.785714285714

now we have:
1.45 is 51.785714285714% of 2.8
