    Answer:

    \frac{11}{96} of an hour.

    Step-by-step 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 = \frac{2}{3} of an hour

    Koran new chatted online with all her friends on Sunday for = \frac{1}{4} of an hour

    Total time of chatting = \frac{2}{3}+ \frac{1}{4}

                                        = \frac{8+3}{12}       ( By taking LCM of 3 and 4 we get 12 )

                                        = \frac{11}{12} of an hour

    Now, She chatted with Penelope for = \frac{1}{8}\ of \frac{11}{12} = \frac{1}{8}\ \times \frac{11}{12} =  \frac{11}{96} of an hour

    Therefore, Koran chat \frac{11}{96} of an hour with Penelope.
