60
To find the least common denominator (LCD) of the fractions 14/15 and 11/12, first identify the denominators: 15 and 12. The prime factorization of 15 is 3 × 5, and for 12, it is 2^2 × 3. The LCD is found by taking the highest power of each prime factor: 2^2 (from 12), 3 (from both), and 5 (from 15). Thus, the LCD is 2^2 × 3 × 5 = 60.
For 7/12 and 7/15 the LCD is 60.
4/12 + 11/15 = 1 1/15
11/12 + 1/3= 11/12 +4/12=15/12 your answer is 15/12 or 1 1/4
LCD(15, 11) = 165.
11 over 12 + 1 over 3= 11 over 12 + 4 over 12 = 15 over 12 or 1 and 3 over 12 or 1 and 1 over 4
LCD(3, 12, 15) = 60
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==========
9/11
18/11 x 5/12 is 15/22
You need at least two fractions to find an LCD.
LCD(15, 12, 4) = 60.
