1.31 is what percent of 3.91 - 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 3.91 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 3.91, so we can write it down as 100%=3.91.
4. We know, that x% equals 1.31 of the output value, so we can write it down as x%=1.31.
5. Now we have two simple equations:
1) 100%=3.91
2) x%=1.31
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%=3.91/1.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.31 is what percent of 3.91

100%/x%=3.91/1.31
(100/x)*x=(3.91/1.31)*x       - we multiply both sides of the equation by x
100=2.9847328244275*x       - we divide both sides of the equation by (2.9847328244275) to get x
100/2.9847328244275=x
33.503836317136=x
x=33.503836317136

now we have:
1.31 is 33.503836317136% of 3.91
