Answer 1

11/96 of an hour.

Explanation:

Answer 2

`(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.
