Let the ratio of grams of hydrogen per gram of carbon in methane be M, we know that:
M = 0.3357 g / 1 g
Next, lets represent the grams of hydrogen per gram of carbon in ethane be E. The final piece of information we have is:
M / E = 4/3
If we cross multiply,
3M = 4E
Now, substituting the value of M from earlier and solving for E,
E = (3 * 0.3357) / 4
E = 0.2518
There are 0.2518 grams of hydrogen per gram of carbon in ethane.

Natural selection and selective breeding can cause both animal and plant changes. The distinction between the two is that natural selection occurs without human intervention, while selective breeding occurs only when humans interfere. As a result, selective breeding is also known as artificial selection.
