The LCD of x, 5, 7, 15 is 105x.
21/24 + 10/24 = 31/24 = 1 and 7/24
The LCD for 7 and 5 is 35
63
3/4 = 12/167/16 = 7/165/8 = 10/16
The LCD of 5/8 and 7/12 is 24.
LCD is 24
=12*(9+5)/7 = 12*14/7 = 12*2 = 24

5/8 + 7/12 = 15/24 + 14/24 = 29/24 = 1 and 5/24.
5/8 + 7/12 = 15/24 + 14/24 = 29/24 = 1 5/24
Yes, you can do 12 + 7 + 5 = 24
5 factors into 1 and 5 6 factors into 2 and 3 Therefore, the least common multiple is 1*2*3*5 = 30 This is what you would use for the LCD, convert the fifths and sixths into thirtieths.
5/8 - 7/12 = 15/24 - 14/24 = 1/24
LCD(7, 5, 10) = 10
For 5/6 and 7/8 the LCD is 24.
The LCD of x, 5, 7, 15 is 105x.
