A) 1/2

B) 1/4

C) 12/17

D) 8/9

Answer 1

Do 3/4 of 2/3

Turn the demoninator into 12 so:

9/12 8/12 so I’m guessing C

Answer 2

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.
