LCD of 9 and 5 = 45 so equivalent fractions are 25/45 and 36/45. The latter is clearly the larger ie four fifths
The LCD for 2/9 and 1/6 is 18.
The LCD of 3/4 and 7/9 is 36.
what you need to do is find the LCD (Least Common Denominator) of 9 and 12. there are a few ways to do this but you can google those. LCD of 9 and 12 is 36 because 9 x 4 = 12 x 3 4/9 x 4 = 16/36 and 1/12 x 3 = 3/36 16/36 - 3/36 = 13/36
LCD(8, 6) = 24

4/15 is one fraction. You need at least two fractions to find something in common.
18
No. The least common denominator cannot be less than the largest denominator.
LCD of 9 and 5 = 45 so equivalent fractions are 25/45 and 36/45. The latter is clearly the larger ie four fifths
9 multiplied by 14 is 126. So believe it or not the LCD of 2/9 and 3/14 is 126.
It has to be 7x9 or 63 or less. There is no number less than 63 which is divisible by both 7 and 9 therefore 63 is the LCD.
The LCD for 2/9 and 1/6 is 18.
The LCD of 3/4 and 7/9 is 36.
For 1/3, 3/4, 5/32, and 8/9, the denominators are 3 (factor 3), 4 (factor 22), 32 (factor 24) and 9 (factor 32). So the LCD is 32 x 9 = 288.
