1.3 is what percent of 16.64 - 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 16.64 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 16.64, so we can write it down as 100%=16.64.
4. We know, that x% equals 1.3 of the output value, so we can write it down as x%=1.3.
5. Now we have two simple equations:
1) 100%=16.64
2) x%=1.3
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%=16.64/1.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.3 is what percent of 16.64

100%/x%=16.64/1.3
(100/x)*x=(16.64/1.3)*x       - we multiply both sides of the equation by x
100=12.8*x       - we divide both sides of the equation by (12.8) to get x
100/12.8=x
7.8125=x
x=7.8125

now we have:
1.3 is 7.8125% of 16.64
