Question

1. Verify the associative property for addition and multiplication for the rational
numbers -1/2, 2/3 and -5/6.
with the proper step​

Answer 1

Step-by-step explanation:

a+(b+c)=(a+b)+c

-1/2+(2/3+ -5/6)=(-1/2+2/3)+ -5/6

-1/2+[(4+ -5)/6]=[(-3+4)/6]+ -5/6

-1/2+ -1/6=1/6+ -5/6

(-3+ -1)/6=(1+ -5)/6

-4/6= -4/6

-2/3= -2/3

LHS=RHS

a×(b×c)=(a×b)×c

-1/2×(2/3×-5/6)=(-1/2×2/3)×-5/6

-1/2×-5/9= -1/3×-5/6

5/18=5/18

LHS=RHS
