Q1.
What is Sumedha observing about her share as each guest comes in?
Answer

She sees that her share keeps getting smaller every time a new guest comes.

2 people1/23 people1/34 people1/45 people1/5
The same dhokla shared by 2, 3, 4 and 5 people. The coloured slice is Sumedha’s share each time.
2 people (Sumedha, Vinayak) → 1/2
3 people (Kumar comes) → 1/3
4 people (Paridhi comes) → 1/4
5 people (Idha comes) → 1/5
Why it happens: The dhokla stays the same size. When it is shared among more people, it is cut into more equal parts, so each part becomes smaller.
Q2.
In which situation will Sumedha get to eat more dhokla: when shared among 9 people or 11 people?
Answer

She gets more when it is shared among 9 people.


9 people → 1/9

11 people → 1/11
The same dhokla cut into 9 equal parts and into 11 equal parts.
9 people → each share = 1/9
11 people → each share = 1/11
1/9 is bigger than 1/11
Why it happens: Cutting the same dhokla into 11 parts makes thinner slices than cutting it into 9 parts. Fewer people means a bigger piece for each one.
Q3.
How many pieces of 1/6 would make a complete dhokla?
Answer

6 pieces of 1/6 make one complete dhokla.

A dhokla cut into 6 equal pieces. All six pieces together make the whole dhokla.
1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6
= 6 pieces of one-sixth
= 1 whole dhokla
Why it happens: 1/6 means the dhokla was cut into 6 equal parts. Putting all 6 parts back gives the dhokla we started with.
Tip: In the same way, 5 pieces of 1/5 and 8 pieces of 1/8 each make one whole.
Q4.
What would be Sumedha's share, if Idha and Vinayak both give their share of dhokla to her?
Answer

Her share would be 3/5 (three-fifths) of the dhokla.

The dhokla in 5 equal parts. The three coloured parts are Sumedha’s share, Idha’s share and Vinayak’s share.
Everyone’s share = 1/5 (5 people)
Sumedha’s own share ……… 1/5
Idha’s share ………………… 1/5
Vinayak’s share …………… 1/5
1/5 + 1/5 + 1/5 = 3/5
Why it happens: She now holds 3 of the 5 equal pieces, so we write 3 above and 5 below.
