0.13 is what percent of 1.25 - 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 1.25 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 1.25, so we can write it down as 100%=1.25.
4. We know, that x% equals 0.13 of the output value, so we can write it down as x%=0.13.
5. Now we have two simple equations:
1) 100%=1.25
2) x%=0.13
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%=1.25/0.13
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.13 is what percent of 1.25

100%/x%=1.25/0.13
(100/x)*x=(1.25/0.13)*x       - we multiply both sides of the equation by x
100=9.6153846153846*x       - we divide both sides of the equation by (9.6153846153846) to get x
100/9.6153846153846=x
10.4=x
x=10.4

now we have:
0.13 is 10.4% of 1.25
