Question

The least common denominator that can be used to add and is 24x2. What value of b is needed to rewrite the first fraction with the LCD?

Answer 1

3 is the answer to the question.

Answer 2

$\frac{x+1}{8x^2}$ and $\frac{2x-3}{12x}$

LCD is 24x^2

we need to find out b when multiply with first fraction to get 3x+3/24x^2

$\frac{x+1}{8x^2} (\frac{b}{b}) =\frac{3x+3}{24x^2}$

We need to find out a number what multiply with 8x^2 to get 24x^2

$8x^2 * 3 = 24x^2$

$\frac{x+1}{8x^2} (\frac{3}{3}) =\frac{3(x+1)}{24x^2}=\frac{3x+3}{24x^2}$

So the value of b is 3
