3.11 is what percent of 15.74 - 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 15.74 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 15.74, so we can write it down as 100%=15.74.
4. We know, that x% equals 3.11 of the output value, so we can write it down as x%=3.11.
5. Now we have two simple equations:
1) 100%=15.74
2) x%=3.11
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%=15.74/3.11
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.11 is what percent of 15.74

100%/x%=15.74/3.11
(100/x)*x=(15.74/3.11)*x       - we multiply both sides of the equation by x
100=5.0610932475884*x       - we divide both sides of the equation by (5.0610932475884) to get x
100/5.0610932475884=x
19.758576874206=x
x=19.758576874206

now we have:
3.11 is 19.758576874206% of 15.74
