Answer: A = 8 or 8a
Explanation:
To find the Least Common Denominator (LCD) of the following list of fractions, 23/8 and -4/a, we need to follow these steps:
Step 1: Determine the factors of the denominators.
The denominator of the first fraction is 8, which can be factored as 2 x 2 x 2.
The denominator of the second fraction is 'a', and it cannot be factored further.
Step 2: Identify the common factors.
There are no common factors between the denominators.
Step 3: Multiply the factors.
To get the LCD, we need to multiply the denominators of both fractions.
LCD = 8 x a = 8a
Therefore, the LCD of the given fractions is 8a.
