6.5 is what percent of 137.7 - 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 137.7 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 137.7, so we can write it down as 100%=137.7.
4. We know, that x% equals 6.5 of the output value, so we can write it down as x%=6.5.
5. Now we have two simple equations:
1) 100%=137.7
2) x%=6.5
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%=137.7/6.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.5 is what percent of 137.7

100%/x%=137.7/6.5
(100/x)*x=(137.7/6.5)*x       - we multiply both sides of the equation by x
100=21.184615384615*x       - we divide both sides of the equation by (21.184615384615) to get x
100/21.184615384615=x
4.720406681191=x
x=4.720406681191

now we have:
6.5 is 4.720406681191% of 137.7
