Step-by-step explanation:

Answer 2

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.
