Question

Show that -4 /3 *(2/5+-7/10)=(-4/3*2/5)+(-4/3*-7/10)

Answer 1

Answer:

hope  it helps u

Step-by-step explanation: We have to prove LHS=RHS

First LHS --> -4/3*(2/5-7/10)

= -4/3*4-7/10 (take LCM)

= -4/3*-3/10

= +12/30----solution 1

Now RHS--> (-4/3*2/5)+(-4/3*-7/10)

= (first solve brackets)  ( -8/15)+(+28/30)

= -16+28/30   (both the brackets are solved and i have taken LCM to solve them)

= +12/30

Hence proved

LHS=RHS
