Answer: The least common denominator of 1/4 and 1/6 is 12.

Prime factorisations of 8= 2 × 2 × 2.

Prime factorisations of 12= 2 × 2 × 3.

Hi!

To find the least common denominator of
\sf{(1)/(2)} and
\sf{(5)/(6)}, we should first find the least common multiple of 2 and 6, which is 6:

Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16...

Multiples of 6: 6, 12, 18, 24...

(all common multiples are in bold-face; all multiples of 6 are in bold-face because all multiples of 6 are also multiples of 2)

· In both sets, 6 is the least common multiple, and it's also the least common denominator.

Hope this made sense to you !!
