3.4 is what percent of 136.4 - 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 136.4 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 136.4, so we can write it down as 100%=136.4.
4. We know, that x% equals 3.4 of the output value, so we can write it down as x%=3.4.
5. Now we have two simple equations:
1) 100%=136.4
2) x%=3.4
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%=136.4/3.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.4 is what percent of 136.4

100%/x%=136.4/3.4
(100/x)*x=(136.4/3.4)*x       - we multiply both sides of the equation by x
100=40.117647058824*x       - we divide both sides of the equation by (40.117647058824) to get x
100/40.117647058824=x
2.4926686217009=x
x=2.4926686217009

now we have:
3.4 is 2.4926686217009% of 136.4
