Answer 1

The LCD is the LCM of the denominators....
So:

the LCM is 12 because 6 goes into 12 and 12 is already a denominator.
the first fraction would remain the same and the second one would convert to 9/12

Answer 8

Think about it like this:

What is the smallest multiple that 12 and 6 will form?
@desmarie yep

36 is a multiple but 12 will be the smallest multiple so 12 is the LCD

Answer 12

Well no.
If it were 24....
2/24 and 12/24 would be your two fractions.... But these can both be simplified further and still have the same denomination

... If it were 12

1/12 and 6/12 <---- this is correct because 12 is a smaller multiple than 24
