Question

Which shows the expressions rewritten with the least common denominator? 5x+3/3x and 7x/2x^2

Answer 1

Answer:

$\frac{10x^2+6x}{6x^2}$ and $\frac{21x}{6x^2}$.

Step-by-step explanation:

The given expression is:

$\frac{5x+3}{3x}$ and $\frac{7x}{3x^2}$.

The least common denominator is: $6x^2$.

We collect  LCM for the denominator to obtain;

$\frac{2x(5x+3)}{6x^2}$ and $\frac{3(7x)}{6x^2}$.

We multiply out the parenthesis to obtain;

$\frac{10x^2+6x}{6x^2}$ and $\frac{21x}{6x^2}$.

Therefore the correct answer is B or the second option.
