15.5 is what percent of 2.75 - 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 2.75 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 2.75, so we can write it down as 100%=2.75.
4. We know, that x% equals 15.5 of the output value, so we can write it down as x%=15.5.
5. Now we have two simple equations:
1) 100%=2.75
2) x%=15.5
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%=2.75/15.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.5 is what percent of 2.75

100%/x%=2.75/15.5
(100/x)*x=(2.75/15.5)*x       - we multiply both sides of the equation by x
100=0.17741935483871*x       - we divide both sides of the equation by (0.17741935483871) to get x
100/0.17741935483871=x
563.63636363636=x
x=563.63636363636

now we have:
15.5 is 563.63636363636% of 2.75
