Question

Using distributive property, solve the following: (а) 287 x 101 (b) 427 x 98​

Answer 1

Explanation:-

a) let 101 be written as ( 100 + 1 )

⇒ 287 × 101

⇒ 287 × ( 100 + 1 )

• using distributive property of addition [  a ( b + c ) = a × b + a × c ]

⇒ ( 287 × 100 ) + ( 287 × 1 )

⇒ 28700 + 287

⇒ 28987

Answer is 28987

b) Let 98 be written as ( 100 - 2 )

⇒ 427 × 98

⇒ 427 × ( 100 - 2 )

• Using distributive property of subtraction [ a ( b - c ) = a × b - a × c ]

⇒ ( 427 × 100 ) - ( 427 × 2 )

⇒ 42700 - 854

⇒ 41846

Answer is 41846
