Definition

What is it?

Sharing between groups, also known as a division word problem, is about distributing a total number of items equally among a certain number of groups. It helps us find out how many items each group gets or how many groups can be formed.

Simple Example

Quick Example

Imagine you have 20 ladoos and you want to share them equally among your 4 friends. To find out how many ladoos each friend gets, you would use sharing between groups, which is division. Each friend would get 5 ladoos.

Worked Example

Step-by-Step

PROBLEM: Your school has 45 new textbooks. These need to be distributed equally among 5 classrooms. How many textbooks will each classroom receive?

STEP 1: Identify the total number of items. Total textbooks = 45.
---
STEP 2: Identify the number of groups. Number of classrooms = 5.
---
STEP 3: Decide what operation to use. Since we are sharing equally, we will use division.
---
STEP 4: Divide the total items by the number of groups: 45 ÷ 5.
---
STEP 5: Perform the division. 45 ÷ 5 = 9.
---
ANSWER: Each classroom will receive 9 textbooks.

Why It Matters

Understanding sharing between groups is crucial for managing resources efficiently, whether it's distributing food aid (Economics) or allocating computing power (AI). This skill is vital for careers in logistics, data science, and even managing your own small business.

Common Mistakes

MISTAKE: Multiplying instead of dividing. Students sometimes multiply the total by the number of groups. | CORRECTION: Remember that 'sharing equally' or 'distributing' always means division. Multiplication is for finding a total when you have groups of equal size.

MISTAKE: Confusing the dividend and divisor. Putting the smaller number first in division. | CORRECTION: Always divide the total (the larger number of items) by the number of groups (the smaller number you are dividing by).

MISTAKE: Forgetting the remainder when items can't be shared perfectly. | CORRECTION: In Class 3, most problems will divide perfectly. Later, you'll learn about remainders, which are the items left over after equal sharing.

Practice Questions

Try It Yourself

QUESTION: A farmer harvested 36 mangoes and wants to pack them into 4 baskets, with an equal number in each. How many mangoes will be in each basket? | ANSWER: 9 mangoes

QUESTION: A train has 72 seats in total, spread equally across 8 compartments. How many seats are in one compartment? | ANSWER: 9 seats

QUESTION: Your mother bought 50 balloons for your birthday party. She wants to give 5 balloons to each guest. How many guests can receive balloons? | ANSWER: 10 guests

MCQ

Quick Quiz

There are 28 chalk sticks to be shared equally among 7 students. How many chalk sticks does each student get?

The Correct Answer Is:

To share 28 chalk sticks equally among 7 students, you divide 28 by 7. 28 ÷ 7 = 4. So, each student gets 4 chalk sticks.

Real World Connection

In the Real World

Imagine you are helping your parents manage their small kirana store. If they receive a box of 100 biscuits and want to make smaller packets of 10 biscuits each, they use this concept (100 ÷ 10 = 10 packets). This helps them decide how many smaller packets to sell.
