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.

The LCD of 1/2 and 2/3 is 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==========
7/10 - 3/15 = 15/30 = 1/2Why?You need to find the LCD (least common denominator) which is 30. Look at the work below. You must keep in mind that whatever you do to the denominator, you must do to the numerator.7/ time 3 = 21/10 time 3 = 30- 3/ time 2 = 6/15 time 2 = -3021 - 6 = 15= 15/30 = 1/27/10 - 3/15 = ?Since 3/15 can be easily reduced to 1/5, we have:7/10 - 1/5 = ?Then, we find the LCD of 5 and 10, which is 10, by multiplying 2 to the numerator and denominator of 1/5:7/10 - 2/10 = 5/10 = 1/2.Another method includes using the basic fraction and finding the LCD:7/10 - 3/15 = ?The LCD (LCM) is 10/5 * 15/5 * 5 = 2 * 3 * 5 = 30. Thus, multiply 3 to the numerator and denominator in 7/10, and 2 to 3/15 in the same fashion.21/30 - 6/30 = 15/30 = 1/2.
No. 1 over 2 = 1/2 = 0.5 8 over 15 = 8/15 = 0.533 Clearly they are not the same.
1/2 + 1/15 = 17/30
3 over 15 = 1 over 5
