1.6 is what percent of 8.1 - 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 8.1 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 8.1, so we can write it down as 100%=8.1.
4. We know, that x% equals 1.6 of the output value, so we can write it down as x%=1.6.
5. Now we have two simple equations:
1) 100%=8.1
2) x%=1.6
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%=8.1/1.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.6 is what percent of 8.1

100%/x%=8.1/1.6
(100/x)*x=(8.1/1.6)*x       - we multiply both sides of the equation by x
100=5.0625*x       - we divide both sides of the equation by (5.0625) to get x
100/5.0625=x
19.753086419753=x
x=19.753086419753

now we have:
1.6 is 19.753086419753% of 8.1
