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?

mother = \(\frac{1}{8}\) × 16 = 2
(c) Number of pieces given to her mother = 16 × \(\frac{1}{4}\) = 4
(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.
