Express the fractions 1/2, 3/16, and 7/8 with an LCD.

LCD is the least common denominator. The least common denominator (LCD) refers to the smallest number that is a common denominator for a given set of fractions.

Answer: The fractions 1/2, 3/16, and 7/8 with an LCD can be expressed as 8/16, 3/16 and 14/16.

We will find the LCM of 2, 16, and 8 to find the LCD

Explanation:

We will list the first few multiples of 2, 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.

So, the common divisor of 2, 16, and 8 is 16.

Thus,

1/2 = 8/16

3/16 = 3/16

7/8 = 14/16

So, the required fractions are 8/16, 3/16 and 14/16.
