1.28 is what percent of 25.46 - 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 25.46 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 25.46, so we can write it down as 100%=25.46.
4. We know, that x% equals 1.28 of the output value, so we can write it down as x%=1.28.
5. Now we have two simple equations:
1) 100%=25.46
2) x%=1.28
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%=25.46/1.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.28 is what percent of 25.46

100%/x%=25.46/1.28
(100/x)*x=(25.46/1.28)*x       - we multiply both sides of the equation by x
100=19.890625*x       - we divide both sides of the equation by (19.890625) to get x
100/19.890625=x
5.0274941084053=x
x=5.0274941084053

now we have:
1.28 is 5.0274941084053% of 25.46
