(ii)Irrational numbers - A number which is not rational, (i.e) cannot be expressed as a ratio or percentage is called as irrational number.

Citrus2011 [14]
Simply divide 23 and 2/5 bags of apples between 9 friends:

23 and 2/5 bags ÷ 9 friends= 117/5 bags ÷ 9 friends
                                              =  13/5 bags
                                              = 2 and 3/5 bags

Therefore, each friend receives 2 and 3/5 bags of apples.

Hope this helps!
