Answer:


(11)/(96) of an hour.

Explanation:

Given:

Koran new chatted online with all her friends on Saturday for = 2/3 of a hour.

Koran new chatted online with all her friends on Sunday for = 1/4 of an hour.

She chatted with Penelope for = 1/8 of the total time.

Question asked:

Which fraction of an hour did Koran apes chatting with Penelope ?

Solution:

Koran new chatted online with all her friends on Saturday for =
(2)/(3) of an hour

Koran new chatted online with all her friends on Sunday for =
(1)/(4) of an hour

Total time of chatting =
(2)/(3)+
(1)/(4)

=
(8+3)/(12) ( By taking LCM of 3 and 4 we get 12 )

=
(11)/(12) of an hour

Now, She chatted with Penelope for =
(1)/(8)\ of (11)/(12) = (1)/(8)\ * (11)/(12) = (11)/(96) of an hour

Therefore, Koran chat
(11)/(96) of an hour with Penelope.
