Answer 1

Take the LOWEST COMMON MULTIPLE of the denominator.

Answer 2

Do you know what LCM is? :)

Answer 3

not really

Answer 4

Okay, so LCM or the lowest common multiple gives you, well, the lowest common multiples of two numbers.

They are REALLY HELPFUL IN FRACTIONS.

So let us say you have 4 and 14.

Now the LCM is one common multiple found in both which is the LEAST.

4 multiplication table = 4 8 12 16 20 24 28 32
14 multiplication table = 14 28 42

Hold on there, if you see, we found a match!!

28 is a COMMON MULTIPLE and is the least as it comes the earliest in the table.

So we say that 28 is the lowest common multiple or LCM of 4 and 14.

Understood? :)
