Answer 1

Hi, This is very easy sum.
Given: a = 4/7 , b = -3/8 , c = -12/13
Verify that a(b+c) = ab + ac
LHS = a(b+c)
b+c = -3/8 + -12/13
b+c = -135/104
a(b+c) = 4/7 × -135/104
= -135/182
RHS = ab + bc
ab = 4/7 × -3/8
= -3/14
ac = 4/7 × -12/13
ac = -48/91
ab + ac = -3/14 + -48/91
= -273-672/1274
= -945/1274. ( divide it by 7)
= -135/182
From LHS and RHS
a(b+c) = ab + ac
Hence Verified

I hope this is correct
