27 is what percent of 6.75 - 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 6.75 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 6.75, so we can write it down as 100%=6.75.
4. We know, that x% equals 27 of the output value, so we can write it down as x%=27.
5. Now we have two simple equations:
1) 100%=6.75
2) x%=27
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%=6.75/27
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27 is what percent of 6.75

100%/x%=6.75/27
(100/x)*x=(6.75/27)*x       - we multiply both sides of the equation by x
100=0.25*x       - we divide both sides of the equation by (0.25) to get x
100/0.25=x
400=x
x=400

now we have:
27 is 400% of 6.75
