Which expression is equivalent to [tex]\(\frac{m-4}{m+4} \div (m+2)\)[/tex]?

A. [tex]\(\frac{m-4}{(m+4)(m+2)}\)[/tex]
B. [tex]\(\frac{(m+4)(m+2)}{m-4}\)[/tex]
C. [tex]\(\frac{(m-4)(m+2)}{m+4}\)[/tex]
D. [tex]\(\frac{m+4}{(m-4)(m+2)}\)[/tex]



Answer :

To determine which expression is equivalent to [tex]\(\frac{m-4}{m+4} \div (m+2)\)[/tex], we need to simplify the given expression step-by-step:

1. Start with the given expression:
[tex]\[ \frac{m-4}{m+4} \div (m+2) \][/tex]

2. Recall that dividing by a number is the same as multiplying by its reciprocal. Using this property, we can rewrite the division as multiplication with the reciprocal of [tex]\(m+2\)[/tex]:
[tex]\[ \frac{m-4}{m+4} \div (m+2) = \frac{m-4}{m+4} \times \frac{1}{m+2} \][/tex]

3. Combine the fractions using the multiplication rule for fractions (multiply the numerators together and the denominators together):
[tex]\[ \frac{m-4}{m+4} \times \frac{1}{m+2} = \frac{m-4}{(m+4)(m+2)} \][/tex]

4. Therefore, the simplified expression is:
[tex]\[ \frac{m-4}{(m+4)(m+2)} \][/tex]

By following these steps, we find that the expression equivalent to [tex]\(\frac{m-4}{m+4} \div (m+2)\)[/tex] is:
[tex]\[ \boxed{\frac{m-4}{(m+4)(m+2)}} \][/tex]
