Numbers in a glide

[superflanker]

Hi!
Some questions that are appearing in performance exams compare a light and a hevier aircraft in a glide.

So, I know the heavy aircraft will have an increased ROD. But what about the descent gradient and angle?

Descent gradient is proportional to ROD (Gradient = ROD/TAS * 6000/6080). So, gradient will also increase?

And what about descent angle? If Gradient = tan(angle) * 100, will this also increase?

Thanks!
