12.99 is what percent of 6.49 - 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 6.49 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 6.49, so we can write it down as 100%=6.49.
4. We know, that x% equals 12.99 of the output value, so we can write it down as x%=12.99.
5. Now we have two simple equations:
1) 100%=6.49
2) x%=12.99
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%=6.49/12.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.99 is what percent of 6.49

100%/x%=6.49/12.99
(100/x)*x=(6.49/12.99)*x       - we multiply both sides of the equation by x
100=0.49961508852964*x       - we divide both sides of the equation by (0.49961508852964) to get x
100/0.49961508852964=x
200.15408320493=x
x=200.15408320493

now we have:
12.99 is 200.15408320493% of 6.49
