Answer:0
Step-by-step explanation:
To simplify the expression (a - b)/ab + (b - c)/bc + (c - a)/ca, we can first find a common denominator for all the fractions. The common denominator in this case is abc.
Expanding each fraction with the common denominator, we get:
[(a - b) * c + (b - c) * a + (c - a) * b] / abc
= [ac - bc + ab - ac + bc - ba] / abc
= 0 / abc
= 0
Therefore, the simplified expression is 0.
