Question

Verify distributive property of multiplication over addition using a = 4/5 , b = 7/5 and c =-7/10 .

Answer 1

Answer:84/50=84/50

Step-by-step explanation:a(b+c)=a×b+a×c

4/5(7/5+7/10)=4/5×7/5+4/5×7/10

LHS

4/5(14+7/10)

4/5(21/10)

4/5×21/10=84/50

RHS

4/5×7/5+4/5+7/10

28/25+28/50

56+28/50=84/50

LHS=RHS

Answer 2

Answer:

Ans: Distributive property of multiplication over addition using a = 4/5 , b = 7/5 and c =-7/10  

So=a x (b + c) =axb + axc

LHS= ax(b+c) =RHS=ab+ac

LHS= 4/5 x( 7/5 +-7/10)

So LCM=10

7x2/5x2 +-7/10

4/5 x (14/10 +-7/10 )

   LHS=   4/5 x 7/10

=  2/5 x 7/5        

=   14/25

RHS=4/5 x 7/5 +  4/5 x-7/10

               =28/25  +  -28/50

LCM=50

=28x2/25x2=56/50

=56/50  + -28/50                                

=    28/50  =14/25
