Do 3/4 of 2/3

Turn the demoninator into 12 so:

9/12 8/12 so I’m guessing C

Answer: The correct option is (D)
(8)/(9).

Step-by-step explanation: Given that
(3)/(4) of Melissa's friends babysit for extra money and
(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=(3)/(4).

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


f=((2)/(3))/((3)/(4))=(2)/(3)*(4)/(3)=(8)/(9).

Thus, the required fraction is
(8)/(9).

Option (D) is CORRECT.
