Express the fractions 3/4, 7/16, and 5/8 with an LCD.
LCD is the least common denominator of a given set of fractions.
Answer: 12/16, 7/16, and 10/16
We will find the LCM of 4, 16, and 8 to find the LCD.
We will list the first few multiples of 4, 16, and 8 and then identify the least among those multiples. The least common multiple will be the least common divisor of the given fractions.
We can see that the common divisor of 4, 16, and 8 is 16. So, the fractions can be converted to like fractions with a common denominator of 16. The given fractions 3/4, 7/16, and 5/8 can be written as 12/16, 7/16, and 10/16
