How Can I Solve Organic Chemistry Synthesis Problems?

[asdfTT123]

I've been staring at these for a while now and I can't seem to get them. I would really appreciate anyone's help with these.

1. Methylcyclohexane -> 1-methyl,2-bromo-cyclohexane (bromine added to ortho carbon in respect to the methyl group). The main problem here is that I don't know where to start!

2, 3. The rest are on the attachment.

Thanks!
