You will just need to study the topic of gear drive trains in general. But the main idea from that question is that the linear tangential velocity of each pairs of gears is equal.

So VA=VB and you should know that v=rω.

Thus rAωA=rBωB and so you can get a ratio of ωBA.

Similarly, for gears to mesh, their modules must be equal

mA=mB

DA/TA= DB/TB

Where D is the diameter of the gear and T is the number of teeth of the gear.

You can check Wikipedia for the topic of "Gear Trains". That should have the basic info and equations to get you started.
