Question

write commutative property associative property of addition and multiplication for a rational number​

Answer 1

COMMUTATIVE =

a+b=b+a

Addition 1/2 + 4/2= 5/2

4/2+1/2=5/2

a×b=b×a

Multiplication 1/3×6/3=6/9=2/3

6/3×1/3=6/9=2/3

ASSOCIATIVE=

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

Addition 4/2+(6/2+8/2)=4/2+14/2= 18/2=9/1

(4/2+6/2)+8/2=10/2+8/2= 18/2=9/1

a×(b×c)=(a×b)×c

Multiplication 4/2×(6/2×8/2)= 4/2×48/2=192/2=96/1

(4/2×6/2)×8/2=24/2×8/2= 192/2= 96/1
