For this case we must express as a single fraction the following expression:
$\frac {1} {a} + \frac {2} {b} + \frac {3} {c}$

We have that the common denominator of the three fractions is given by: abc

So, to express as a fraction we divide abc by each denominator and multiply by each numerator, obtaining:

$\frac {bc + 2ac + 3ab} {abc}$

Answer:

$\frac {bc + 2ac + 3ab} {abc}$
