When two fractions with different denominators are to be added
using the standard procedure, which of these must first be found?
A) The GCF (Greatest Common Factor) of the fractions
B) The prime factorization of the fractions’ numerators
C) The LCD (Least Common Denominator) of the fractions (Correct Answer)
D) The mean value of the denominators
Explanation:
In order to add fractions with different denominators using the standard procedure,
the Least Common Denominator (LCD) must be found. That way only the numerators of
the fractions need to be added.
