Equal Groups Chapter Overview

This chapter talks about how multiplication and division are related. Instead of viewing them as separate rules, students learn that multiplication is repeated addition (adding the same number multiple times), while division is repeated subtraction (taking away the same amount until zero is reached).

The chapter uses scenarios that kids may relate to, like animals hopping on a number line or kids weaving necklaces, to explain how to group things into sets. By the end of this unit, learners will understand how to:

• Create multiplication tables using smaller, simpler tables.

• You can use skip-counting to figure out division difficulties.

• Arrange objects in rows and columns to find the total count quickly.

Equal Groups Class 4 NCERT Solutions

To make learning easier and exam-focused, here are solutions arranged based on NCERT exercise patterns and pages.

NCERT Page 128–130: Animal Jumps (Skip Counting)

In this part, you will learn how to utilise division to find the number of hops.

Frog (jumps of 2):

• To reach 20 → 20 ÷ 2 = 10 jumps

• To reach 30 → 30 ÷ 2 = 15 jumps

Squirrel (jumps of 3):

• To reach 27 → 27 ÷ 3 = 9 jumps

• To reach 36 → 36 ÷ 3 = 12 jumps

Rabbit (jumps of 5):

• To reach 25 → 25 ÷ 5 = 5 jumps

• To reach 40 → 40 ÷ 5 = 8 jumps

We used the idea that multiplication is adding numbers over and over again and division is counting jumps.

NCERT Page 131–133: Division and Equal Sharing

These questions are about splitting things into groups of the same size.

Example 1: Sea Shells

• Total shells = 112

• Shells per necklace = 28

• Number of necklaces = 112 ÷ 28 = 4

Final Answer: 4 necklaces

Example 2: Laddoos in Small Boxes

• Total laddoos = 80

• Laddoos per box = 4

• Number of boxes = 80 ÷ 4 = 20

Final Answer: 20 boxes

Example 3: Laddoos in Big Boxes

• Total laddoos = 80

• Laddoos per box = 20

• Number of boxes = 80 ÷ 20 = 4

Final Answer: 4 boxes

Example 4: Bananas Sharing

• Total bananas = 25

• Monkeys = 5

• Bananas per monkey = 25 ÷ 5 = 5

Final Answer: Each monkey gets 5 bananas

These questions are about splitting things into groups of the same size.

Example 1: Rows and Columns

• 4 rows with 7 objects each

• Total objects = 4 × 7 = 28

Final Answer: 28 objects

Example 2: Legs Counting (Cats)

• Total legs = 28

• Legs per cat = 4

• Number of cats = 28 ÷ 4 = 7

Final Answer: 7 cats

Example 3: Weeks Calculation

• Total days = 21

• Days in a week = 7

• Number of weeks = 21 ÷ 7 = 3

Final Answer: 3 weeks

Example 4: Kangaroo Jumps

• Total distance = 150

• Jump size = 30

• Number of jumps = 150 ÷ 30 = 5

Final Answer: 5 jumps

How Many Jumps? – Skip Counting on the Number Line

The chapter begins with animals jumping on a number line to introduce the concept of multiples.

The Frog's Jumps

• A Frog jumps 2 steps at a time:

• Starting from 0, the frog touches: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30.

• Question: To reach 30, how many jumps does he take?

• Answer: 30 ÷ 2 = 15 jumps.

The Squirrel's Jumps

• A Squirrel jumps 3 steps at a time:

• The squirrel touches: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30.

• Question: How many jumps to reach 27?

• Answer: 27 ÷ 3 = 9 jumps.

• Question: To reach 36?

• Answer: 36 ÷ 3 = 12 jumps.

The Rabbit's Jumps

• A Rabbit jumps 5 steps at a time:

• The rabbit touches: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50.

• Question: To reach 25, how many jumps?

• Answer: 25 ÷ 5 = 5 jumps.

• Question: He reaches 40 after how many jumps?

• Answer: 40 ÷ 5 = 8 jumps.

Sea Shells: Division as Repeated Subtraction

This section of chapter 9 explores how to divide large numbers by taking away equal groups.

Problem: Kanu has 112 sea shells. He wants to make necklaces with 28 shells each. How many necklaces can he make?

• Total shells: 112

• First Necklace: 112 - 28 = 84 shells remaining.

• Second Necklace: 84 - 28 = 56 shells remaining.

• Third Necklace: 56 - 28 = 28 shells remaining.

• Fourth Necklace: 28 - 28 = 0 shells remaining.

Answer: Kanu can make 4 necklaces from 112 shells.

Gangu’s Sweets: Packaging Logic

Gangu is preparing laddoos for a festival and needs to pack them into different sized boxes.

• Problem 1: Gangu has 80 laddoos in a tray. He packs 4 laddoos in each small box. How many small boxes are needed?

• Calculation: 80 ÷ 4 = 20.

• Answer: 20 small boxes.

• Problem 2: If Gangu packs 20 laddoos in a big box, how many big boxes will he need for 80 laddoos?

• Calculation: 80 ÷ 20 = 4.

• Answer: 4 big boxes.

• Problem 3: If Gangu has 60 laddoos and needs to pack boxes of 5, how many boxes?

• Calculation: 60 ÷ 5 = 12 boxes.

Class 4 Maths Chapter 9 Question Answer

Here are the remaining textbook solutions for students to practise:

Minku’s Laddoos

Minku has 15 laddoos. She wants to put them equally into 5 boxes.

• Question: How many laddoos per box?

• Calculation: 15 ÷ 5 = 3.

• Answer: 3 laddoos in each box.

• Question: If she uses only 3 boxes, how many in each?

Equal groups Class 4 Question Answer Tips

To do well in this chapter, remember these last few things:

• Adding is the same as multiplying: When you have equal groups, multiplying is the quickest approach to determine the total.

• Sharing is dividing: When you divide, you just break a big sum into smaller, equal portions.

• Repeated Subtraction: For hard division issues, keep taking away the same number until you get to zero.

• Patterns Matter: Multiplication tables have patterns (like the table of 5 ending in 0 or 5) that help in checking your answers.

• Flexible Tables: You can create any multiplication table by adding the results of two smaller tables together.
