1.8 is what percent of 25.4 - 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 25.4 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 25.4, so we can write it down as 100%=25.4.
4. We know, that x% equals 1.8 of the output value, so we can write it down as x%=1.8.
5. Now we have two simple equations:
1) 100%=25.4
2) x%=1.8
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%=25.4/1.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.8 is what percent of 25.4

100%/x%=25.4/1.8
(100/x)*x=(25.4/1.8)*x       - we multiply both sides of the equation by x
100=14.111111111111*x       - we divide both sides of the equation by (14.111111111111) to get x
100/14.111111111111=x
7.0866141732283=x
x=7.0866141732283

now we have:
1.8 is 7.0866141732283% of 25.4
