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

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: $$\frac{[L]}{[T]} \times [T]$$
