Example: 1/30 and 1/42
Their LCD is 210.
Multiply each one by whatever it takes to make 210 in the denominator.
30 x 7 = 210
42 x 5 = 210
1/30 x 7/7 = 7/210
1/42 x 5/5 = 5/210
2/3,3/8Find the LCD. The LCD of 3 and 8 is 24. Multiply the fractions by whatever it takes to make 24.2/3 x 8/8 = 16/243/8 x 3/3 = 9/24
The LCD for fractions is the LCM (least common multiple) of all of the denominators.

Ordinarily, one finds the least common denominator (LCD) of a set of common fractions in order to add or subtract the set of fractions. The LCD is the least common multiple (LCM) of the denominators of the set of fractions. Without knowing whatis to be multiplied by the LCD, and why, this question is ambiguous.

LCD means lowest common denominator which is needed when adding or subtracting fractions that have different denominators.
You need at least two fractions to find an LCD. If that's 5/7 and 1/2, the LCD is 14.
express the fractions 3/4, 7/16 and 5/8 with the LCD. the answer is b) 12/16,7/16,and 10/16 OR c)9/16,49/16, and 36/16
