Class 4 Maths Chapter 4 Question Answer

What does 45 ones make?

Answer:
45 ones = 4 tens + 5 ones = 45.

How do you write 7 thousand, 0 hundreds, 2 tens and 4 ones?

Answer:
7 thousands = 7,000
0 hundreds = 0
2 tens = 20
4 ones = 4

So, the number is:

7,000 + 0 + 20 + 4 = 7,024

How much more is needed to make 1,000 from 850?

Answer:

1,000 − 850 = 150

So, 150 more is needed to make 1,000.

How do you compare four-digit numbers?

Answer:
Compare the digits from the thousands place first. If the thousands digits are the same, compare the hundreds, then tens, and finally ones.

For example:

2,190 < 2,910

Both numbers have 2 thousands. The hundreds digits are 1 and 9, so 2,910 is greater.

What is the expanded form of 3,452?

Answer:

3,452 = 3,000 + 400 + 50 + 2

What is the expanded form of 4,085?

Answer:

4,085 = 4,000 + 0 + 80 + 5

The zero in the hundreds place is important because it shows that there are no hundreds.

Thousands Around Us Class 4

The chapter Thousands Around Us introduces four-digit numbers and extends students' understanding of place value from hundreds to thousands. The current Class 4 Math-Mela chapter uses everyday situations, including a community lunch, to introduce numbers around 1,000 and beyond.

Students learn:

Ones, tens, hundreds, and thousands
Grouping and regrouping
Four-digit numbers
Place value
Number names
Expanded form
Comparing numbers
Ordering numbers
Number lines
Adding or subtracting from a number
Making numbers using given digits

Place Value in Thousands Around Us

A four-digit number can have thousands, hundreds, tens, and ones.

Thousands	Hundreds	Tens	Ones
3	4	5	2

The number is 3,452.

Its expanded form is:

3,000 + 400 + 50 + 2

The place value of each digit is:

3 → 3,000
4 → 400
5 → 50
2 → 2

Grouping and Regrouping

Regrouping helps us understand how smaller units form larger units.

10 ones = 1 ten
10 tens = 1 hundred
10 hundreds = 1 thousand

Therefore:

1,000 = 10 hundreds = 100 tens = 1,000 ones

For example, 11 tens and 14 ones can be regrouped as:

11 tens = 110
14 ones = 14

110 + 14 = 124

So, 11 tens and 14 ones make 124.

Writing Numbers in Thousands Around Us

When writing a four-digit number, each digit must be placed in its correct position.

For example:

4 thousands + 0 hundreds + 8 tens + 5 ones = 4,085

The zero is used as a place holder for the hundreds position.

Number Names and Expanded Forms

Number	Expanded Form	Number Name
1,001	1,000 + 1	One Thousand One
3,452	3,000 + 400 + 50 + 2	Three Thousand Four Hundred Fifty-Two
4,085	4,000 + 80 + 5	Four Thousand Eighty-Five
5,010	5,000 + 10	Five Thousand Ten

Comparing and Ordering Numbers

To compare four-digit numbers, start with the thousands place.

For example:

4,500 > 4,050

Both numbers have 4 thousands. Their hundreds digits are 5 and 0, so 4,500 is greater.

Similarly:

2,190 < 2,910

because 9 hundreds are greater than 1 hundred.

Greater Than, Less Than and Equal To

Use these symbols when comparing numbers:

> means greater than
< means less than
= means equal to

Examples:

5,200 > 4,900
3,245 < 3,425
6,000 = 6,000

1895 Increase the Number by 1

The GSC query “1895 increase the number by 1” is generating a strong position and specific search demand, so the answer should be direct.

1,895 + 1 = 1,896

Therefore, increasing 1,895 by 1 gives 1,896.

Identify Things Around You That Are More Than 1000 in Number

Numbers greater than 1,000 can be found in many everyday situations. For example:

Number of people attending a large event
Number of books in a large library
Number of seats in a large stadium
Number of trees in a large area
Distance measured in metres

The purpose of this activity is to help students connect four-digit numbers with quantities they see around them.

Making Four-Digit Numbers

Suppose the digits 2, 3, 4, and 7 are given and each digit must be used once.

The number of different four-digit arrangements is:

4 × 3 × 2 × 1 = 24

Therefore, 24 different four-digit numbers can be formed when all four digits are used exactly once.

Number Line and Thousands

A number line helps students understand the order and position of numbers.

For example:

1,040 < 1,043 < 1,050

Therefore, 1,043 lies between 1,040 and 1,050.

When comparing larger numbers, the same place-value rule applies. Start from the thousands place and move towards the ones place until the digits are different.
