3.19 is what percent of 39.4 - 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 39.4 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 39.4, so we can write it down as 100%=39.4.
4. We know, that x% equals 3.19 of the output value, so we can write it down as x%=3.19.
5. Now we have two simple equations:
1) 100%=39.4
2) x%=3.19
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%=39.4/3.19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.19 is what percent of 39.4

100%/x%=39.4/3.19
(100/x)*x=(39.4/3.19)*x       - we multiply both sides of the equation by x
100=12.351097178683*x       - we divide both sides of the equation by (12.351097178683) to get x
100/12.351097178683=x
8.0964467005076=x
x=8.0964467005076

now we have:
3.19 is 8.0964467005076% of 39.4
