LCD(12, 20) = 60
LCD(9, 28) = 252
60
240
120
2/12=1/6 The LCD of 1/6 and 3/4=The LCD of 1/6 and 1/4=12 Therefore, 2/12 and 9/12 have the same denominator. They are equal to the original fractions. LCD=12
The LCD of 20 and 9 is 180.
lcd(2, 6, 12) = 12.
The LCD of 5 and 4 is 20.
LCD(12, 8) = 24.
Assume an additive expression.X5 + X3X3(X2 + 1)--------------------so,X3====Is the LCD
The LCD of 7 and 20 is 140
