1.56 is what percent of 12.9 - 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 12.9 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 12.9, so we can write it down as 100%=12.9.
4. We know, that x% equals 1.56 of the output value, so we can write it down as x%=1.56.
5. Now we have two simple equations:
1) 100%=12.9
2) x%=1.56
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%=12.9/1.56
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.56 is what percent of 12.9

100%/x%=12.9/1.56
(100/x)*x=(12.9/1.56)*x       - we multiply both sides of the equation by x
100=8.2692307692308*x       - we divide both sides of the equation by (8.2692307692308) to get x
100/8.2692307692308=x
12.093023255814=x
x=12.093023255814

now we have:
1.56 is 12.093023255814% of 12.9
