anonymous · Answer

for you 3/2 and 2/3 example, both 2 and 3 go into 6 or 12, you could use either as a LCD

anonymous · Answer

Right so what they both can go into which is six

you find a lcm, least common multiple of the numbers and then multiply all numerators so that the denominators have the same base
