(a) 1,01987 < 8,91,001
(b) 8094 < 91,000
(c) 4873 < 6945
(d) 7651 < 8198
The smaller number come to left on number line
Question no – (4)
Solution :
(a) 6 + 7
(b) 15 – 7
(c) 4 × 5
(d) 12 ÷ 6
Natural Numbers and Whole Numbers Exercise 3B Solution :
Question no – (1)
Solution :
(a) Addition commutative
(b) Multiplication Commutative
(c) Distributive property
(d) Associative of addition
(e) Distributive property
(f) Distributive property
Question no – (2)
Solution :
(a) 8
(b) 487
(c) 2000
(d) 100
(e) 251
Question no – (3)
Solution :
(a) (32 ÷ 8) ÷ 2
= 4 ÷ 2
= 2
= 32 ÷ (8 ÷ 2)
= 32 ÷ 4
= 8
∵ 2 ≠ 8
Hence, – False
(b) 3 × (6 + 1)
= 3 × 7
= 21
= 3 × 6 + 3 × 1
= 18 + 3
= 21
Thus, – True
(c) (25 – 5) × 4
= 20 × 4
= 80
= 25 × 4 + 5 × 4
= 100 + 20
= 120
∴ 80 ≠ 120
Hence, – False
(d) (9 × 8) × 0
= 72 × 0
= 0
= 9 × (8 × 0)
= 9 × 0
= 0
∴ 0 = 0
Therefore, – True
Question no – (4)
Solution :
(a) 250 × 40 × 38
= 10,000 × 38
= 38,000
(b) 8 × 125 × 693
= 1000 × 693
= 6, 93, 000
(c) 5 × 60 × 439
= 300 × 439
= 1,31700
(d) 2 × 50 × 8 × 125 × 4
= 100 × 1,000 × 4
= 4,00,000
Question number – (5)
Solution :
(a) 24598 × 159 – 24598 × 59
= 24598 (159 – 59)
= 24598 × 100
= 23,59,800
(b) 61725 (92 + 8)
= 61725 ( 92 + 8)
= 61725 × 100
= 6, 17,2500
Question number – (6)
Solution :
Greatest 4 digit number
= 9999
Greatest 3 digit number
= 999
= 9999 × 999
= 9999 × (1000 – 1)
= 9999000 – 9999
= 99,89,001
Question number – (7)
Solution :
Total × expenditure for dance
= 12 × 4500
Total expenditure for badminton
= 12 × 1750
So, Now total expenditure for one given year
= 12 × 4500 + 12 + 1750
= 12 (4500 + 1750)
= 12 × 6250
= Rs 75,000
Natural Numbers and Whole Numbers Exercise 3C Solution :
Question no – (2)
Solution :
(a) 6 × 2 – 5 = 7
7 × 3 – 12 = 9
8 × 4 – 21 = 9
9 × 5 – 32 = 13
10 × 6 – 45 = 15
(b) 5 × 11 = 55
55 × 101 = 5555
555 × 1001 = 5,55,555
5555 × 10,001 = 5,55,55,555
55555 × 100001 = 5,55,55,55,555
Question number – (3)
Solution :
8 × 1 + 1 = 9 = 3 × 3
8 × 3 + 1 = 25 = 5 × 5
8 × 6 + 1 = 49 = 7 × 7
8 + 10 + 1 = 81 = 9 × 9
8 × 15 + 1 = 121 = 11 × 11
8 × 21 + 1 = 169 = 13 × 13
8 × 28 + 1 = 225 = 15 × 15
(121 – 1) = 120 = 120 ÷ 8 = 15
(169 – 1) = 168 ÷ 8 = 21
(225 – 1) = 224 ÷ 8 = 28
