Question

What is the lcd of 1/12 and 2/9

Answer 1

Answer:

36

Step-by-step explanation:

The least common denominator is 36. As we can see for the multiples of 12:

12 24 36 48 ...

and the multiples of 9:

9 18 27 36 45 ...

You can also do this by prime factorization:

12=2*2*3

9=3*3

therefore the lcd must be 2*2*3*3=36
