Question 4.

Neha’s uncle brought a chocolate which looks as following diagram:

(a) Neha gave half part of her chocolate to her sister Nidhi. How many pieces of chocolate will she give to Nidhi?

(d) Number of pieces she will get for herself = 16 – (8 + 2 + 4)

= 16 – 14 = 2 .

Question 5.

Arjun studies in 5th class. He spends his day according to the following schedule.

- One fourth of a day in the school.
- One third of a day for sleeping.
