0.15 is what percent of 2.55 - 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 2.55 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 2.55, so we can write it down as 100%=2.55.
4. We know, that x% equals 0.15 of the output value, so we can write it down as x%=0.15.
5. Now we have two simple equations:
1) 100%=2.55
2) x%=0.15
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%=2.55/0.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.15 is what percent of 2.55

100%/x%=2.55/0.15
(100/x)*x=(2.55/0.15)*x       - we multiply both sides of the equation by x
100=17*x       - we divide both sides of the equation by (17) to get x
100/17=x
5.8823529411765=x
x=5.8823529411765

now we have:
0.15 is 5.8823529411765% of 2.55
