1.31 is what percent of 20.99 - 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 20.99 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 20.99, so we can write it down as 100%=20.99.
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%=20.99
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%=20.99/1.31
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 20.99

100%/x%=20.99/1.31
(100/x)*x=(20.99/1.31)*x       - we multiply both sides of the equation by x
100=16.022900763359*x       - we divide both sides of the equation by (16.022900763359) to get x
100/16.022900763359=x
6.2410671748452=x
x=6.2410671748452

now we have:
1.31 is 6.2410671748452% of 20.99
