LCD(25, 20, 4) = 100.
LCD(18, 4, 20) = 180
Solution: 20+25=? 20x.2=4 20+4=24 ans.
To find the least common denominator (LCD) of one quarter (1/4) and three tenths (3/10), first determine the denominators, which are 4 and 10. The multiples of 4 are 4, 8, 12, 16, 20, and the multiples of 10 are 10, 20, 30. The smallest common multiple of both numbers is 20, so the LCD is 20.
25/20. Divide both top and bottom by 5.5/4 or 1 and 1/4

The LCD of 5 and 4 is 20.
Lcd of 5,4,2 is 20 because 5*4=20 and 2*10=20
It is: 100 which is also their LCM

Since 5x + 20 is a multiple of x + 4, it is automatically the LCD of this problem.
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.
LCD is the lowest number all of the given numbers evenly fits int. The answer is 20
