19 is prime, so multiply 19 by 112.
LCM(6, 20, 19) = 1140
The LCD of 9/20 and 19/46 is 460.
A common denominator is 209, as is any multiple of 209.
1/5 + 3/4 First you have to find the common Denominator. The common denominator is 20. 1/5 = 4/20 (5x4=20, so you have to multiply the 1 by 4 as well) 3/4=15/20 (4x5=20 and 3x5=15) Now that you know your common denominator is 20, you can now add your fractions. 4/20 + 15/20 = 19/20 (you only add the numerator, the denominator stays the same) so, your answer is...... 19/20
38 is.

It is 76
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions.

19
It is not possible to give a sensible answer to this question. The least common denominator (LCD) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!
lcd(8, 19) = 152.
It is: 1330

It is: 95
19 is prime, so multiply 19 by 112.
