What could the expression p+0.15p/2 represent including units

So the given is p + 0.15p/2. First, find the least common multiple as the denominator of the sum. That would be 2. Then, for each term, divide the lcm with the term's denominator and multiply it with the numerator. For example, for the term p, it would be (2:1) * p = 2p. Hence the sum would be:

(2p + 0.15p) / 2

(2.15p/2

1.075p

The final expression is 1.075p.
