Question

3/x, 2/x-11. Find LCD

Answer 1

Explanation:

The least common denominator (LCD) is defined as the least common multiple of the denominators of a set of fractions. In this case, we have the fractions:

$\frac{3}{x}, \frac{2}{x-11}$

So the LCD here is the product of $x \ and \ x-11$. Therefore:

$LCD=x(x-11)$

So we can write equivalent expressions as:

$\frac{3(x-11)}{x(x-11)}, \frac{2x}{x(x-11)}$

As you can see, both expression has the same denominator which is the LCD.
