6.5 is what percent of 231 - 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 231 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 231, so we can write it down as 100%=231.
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%=231
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%=231/6.5
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 231

100%/x%=231/6.5
(100/x)*x=(231/6.5)*x       - we multiply both sides of the equation by x
100=35.538461538462*x       - we divide both sides of the equation by (35.538461538462) to get x
100/35.538461538462=x
2.8138528138528=x
x=2.8138528138528

now we have:
6.5 is 2.8138528138528% of 231
