LCD is probably a typo for LCM. The least common divisor of any number is 0 since 0 is the smallest natural number and divides all numbers.
The LCM of two rational algebraic expressions is often used to add or subtract the two expressions. The method used is to identify all common factors in the denominator of the expressions, and multiply the numerators by the uncommon factors (exactly like you would for non-algebraic fractions).
example:
(2/(a+b)xyz) + (4/(a+b)cdz)
the common factors are (a+b), and z. You must multiply the left expression by cd, and the right expression by xy to get
(2cd+4xy) / (a+b)cdxyz

How would you find the LCD when adding or subtracting rational expressions with different denominators?
No
How do you find the LCD of algebraic fractions?
3/5 and 3/20you need to find the LCM of 5 and 20 multiples of 5: 0,5,10,15,20 multiples of 20: 0,20,40,60,80 the LCM of thedenominators,5 and 20, is 20
How do you determine which rational number is greater by rewriting each pair of fractions using their lcd?
Lol im just wasting your time.....just go eat some pie dude
What is the difference between lcd and LCM?
LCD is where you find the LCM of the denominator of a fraction..Least Common Multiple(LCM) works this way:the LCM of 3, 6, 9 is:3=3, 6, 9, 12, 15, 18, 21, 24, 27, 30;6=12, 18, 24, 30, 36, 42, 48, 54, 60;9=9, 18, 27, 36, 45, 54, 63, 72, 81, 90;18 is the LCM since 18 is the smallest multiple of the three numbersso that's it.. LCD works this way:it is used in fractions.. example:the LCD of:1/32/61453/9is:the LCM of the denominator of the three numbers is 18.(18/9) x 1453 = n.(18/6) x 2 = o.(18/3) x 1 = p.n + o + p = LCD/18..
