2. Fill in the blanks :
(i) In 24,673, the place value of 6 is ………..
(ii) In 8,039, the place value of 8 is …………..
(iii) In 3,25, 648, the local value of 5 is ……………
(iv) In 6,439, the local value of 6 is ……….

Solution:

(i) In 24, 673, the place value of 6 is 6 × 100

= 600

(ii) In 8, 039, the place value of 8 is 8 × 1000

= 8000

(iii) In 3, 25, 648, the local value of 5 is 5 × 1000

= 5000

(iv) In 6, 439, the local value of 6 is 6 × 1000

= 6000

3. Find the difference between the place values of 3 and 5 in the number 3945.

Solution:

Place value of 3 in 3945 is 3000

Place value of 5 in 3945 is 5

Difference between them = 3000 – 5

= 2995

Hence, the difference between the place value of 3 and 5 in the number 3945 is 2995

4. In the number 40562
(i) the local value of 5 = …………..
(ii) the place value of 6 = ………..
(iii) the sum of the place value of 5 and the place value of 6 = …………

Solution:

(i) The local value of 5 = 500

(ii) The place value of 6 = 60

(iii) The sum of the place value of 5 and the place value of 6 = 500 + 60

= 560

5.Read and write the following numbers in words and also in expanded form :
(i) 35,000 = …………
(ii) 76,000 = ……………
(iii) 6,23,000 = ………….
(iv) 40,075 = …………….
(v) 50,004 = ………..

Solution:

(i) 35,000 = Thirty five thousands

3 × 10000 + 5 × 1000

(ii) 76, 000 = Seventy six thousands

7 × 10000 + 6 × 1000

(iii) 6, 23, 000 = Six lakhs twenty three thousands

6 × 100000 + 2 × 10000 + 3 × 1000

(iv) 40, 075 = Forty thousand seventy five

4 × 10000 + 7 × 10 + 5 × 1

(v) 50, 004 = Fifty thousand four

5 × 10000 + 4 × 1

6. Find the difference in the place values of two sevens in the number 8, 72, 574.

Solution:

In the number 8, 72, 574 the first 7 occurs at thousand place

Its place value is 70000

The second 7 occurs at tens place

Its place value is 70

The difference of the two place value of 7 = 70000 – 70

= 69930

Hence, the difference in the place value of two 7 in number 872574 is 69930
