Sharing and Measuring
Equal shares
Share Sumedha's mother's dhokla into equal parts.
In your book, Maths Mela (Chapter 5), Sumedha's mother makes a yummy dhokla and asks the children to share it equally. Sumedha and Vinayak cut it into two equal parts: half for Sumedha and half for Vinayak. Each gets 1/2, and 2 halves make the whole dhokla.
Ding dong! The doorbell rings, and Kumar arrives. Now the dhokla is shared equally among 3 children. Each gets one-third, written 1/3. Three thirds make the whole dhokla. Ding dong! Sumedha's cousin Paridhi arrives. Now there are 4 children, so the dhokla is cut into 4 equal parts, and each gets one-fourth, 1/4.
Ding dong! Their neighbour Idha arrives. Now 5 children share, and each gets 1/5, one-fifth. Sumedha says, 'An even smaller slice for me now!' When 5 pieces of 1/5 are joined, they make the whole dhokla again.
The rule is: when one whole is shared equally among some people, each person gets 1 over that number. Shared among 8, each gets 1/8. Shared among 9, each gets 1/9. And the bottom number also tells how many pieces make the whole: 6 pieces of 1/6 make one whole dhokla.
