C) 12/17

D) 8/9

Answer 1

Answer:  The correct option is (D) $\dfrac{8}{9}.$

Step-by-step explanation:  Given that $\dfrac{3}{4}$ of Melissa's friends babysit for extra money and $\dfrac{2}{3}$ of her friends babysit and pet sit.

We are to find the fraction of her friends those who babysits also pet sits.

Total fraction of Melissa's friends is given by

$F=\dfrac{3}{4}.$

Therefore, the fraction of her friends those who babysits also pet sits is given by

$f=\dfrac{\frac{2}{3}}{\frac{3}{4}}=\dfrac{2}{3}\times\dfrac{4}{3}=\dfrac{8}{9}.$

Thus, the required fraction is $\dfrac{8}{9}.$

Option (D) is CORRECT.
