Units of Calculation: Conversion Questions

[parcerita]

I have never been good at doing this in physics so I want to make sure I'm doping this right. The question asks:

What units would result from each of the following calculations?

a) 3cm/s x 25s
b) 4m² ÷ 6s
c) 15m/s² x 2s
d) 5m/s ÷ 3s
e) 3g ÷ 2cm³
f) 1.6kg/m² ÷ 4m

This are what I think are the answers for some:

a) cm/s²
c) m/s³

The division ones I really I'm not sure. Please help.

Ok with these it helps if you can turn the units into algebraic quantities and deal with them in that manner. So for part a) we have a length [L] divided by a time [T] then multiplied by a time [T]

can you simplify: \frac{[L]}{[T]} \times [T]
