25.5 is what percent of 150 - 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 150 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 150, so we can write it down as 100%=150.
4. We know, that x% equals 25.5 of the output value, so we can write it down as x%=25.5.
5. Now we have two simple equations:
1) 100%=150
2) x%=25.5
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%=150/25.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25.5 is what percent of 150

100%/x%=150/25.5
(100/x)*x=(150/25.5)*x       - we multiply both sides of the equation by x
100=5.8823529411765*x       - we divide both sides of the equation by (5.8823529411765) to get x
100/5.8823529411765=x
17=x
x=17

now we have:
25.5 is 17% of 150
