## AP State Syllabus 6th Class Maths Solutions 2nd Lesson Whole Numbers Exercise 2.2

Question 1.
Find the sum by suitable rearrangement.
i) 238 + 695 + 162
ii) 154 + 197 + 46 + 203
i) 238 + 695 + 162 = 238 + 162 + 695 (Commutative property)
= (238 + 162) + 695 (Associative property)
= 400 + 695
= 1095

ii) 154 + 197 + 46 + 203 = 154 + 46 + 197 + 203 (Commutative property)
= (154 + 46) + (197 + 203) (Associative property)
= 200 + 400
= 600 Question 2.
Find the product by suitable rearrangement.
i) 25 × 1963 × 4
ii) 20 × 255 × 50 × 6
i) 25 × 1963 × 4 = 25 × (1963 × 4)
= 25 × (4 × 1963) (Commutative property)
= (25 × 4) × 1963 (Associative property)
= 100 × 1963 = 196300

ii) 20 × 255 × 50 × 6 = 20 × 50 × 255 × 6 (Commutative property)
= (20 × 50) × (255 × 6) (Associative property)
= 1000 × 1530
= 15,30,000

Question 3.
Find the product using suitable properties.
1)205 × 1989 ii) 1991 × 1005
i) 205 × 1989 = (200 + 5) × 1989
(Distributive property of multiplication over addition)
= (200 × 1989) + (5 × 1989)
= 397800 + 9945
= 407745

ii) 1991 × 1005
= 1991 × (1000 + 5)
Distributive property of multiplication over addition.
= (1991 × 1000)+ (1991 × 5)
= 1991000 + 9955
= 2000955 Question 4.
