What is the lcd for 1 over 2 and 5 over 6?
2/3 and 3/4Looks like 12 here, so use form of one to convert both fractions to LCD form.4*2/4*3 and 3*3/3*48/12 and 9/12==========
What is LCD of 9 and 15?
the answer is 45. You compute it by reducing each number to its prime factors, and taking the unique set. 9 factors to 3x3, 15 to 3x5, so the unique set is one 3 from the 9, one 3 that they share and one 5 from the 15. 3x3x5=45. Of course, 135 is also a common denominator but isn't the least. you can always find a CD by multiplying the two. The LCD will make simplification after the addition or subtraction of fractions much easier.
