1.3 is what percent of 31.3 - 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 31.3 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 31.3, so we can write it down as 100%=31.3.
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%=31.3
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%=31.3/1.3
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 31.3

100%/x%=31.3/1.3
(100/x)*x=(31.3/1.3)*x       - we multiply both sides of the equation by x
100=24.076923076923*x       - we divide both sides of the equation by (24.076923076923) to get x
100/24.076923076923=x
4.1533546325879=x
x=4.1533546325879

now we have:
1.3 is 4.1533546325879% of 31.3
