Question

Check the commutative property for addition and multiplcation of the rational numbers -10/11 and 9/33​

Answer 1

Step-by-step explanation:

Note:

Commutative property of addition and multiplication says

• a+b = b+a
• a×c = b×a

Given:

a = -10/11

b = 9/33

Solution:

a+b = b+a

LHS = a+b

= -10/11+9/33

= (-30+9)/33

= -21/33

RHS = b+a

= 9/33+(-10/11)

= 9/33 - 10/11

= (9-30)/33

= -21/30

Hence LHS=RHS Verified

a×b = b×a

LHS = -10/11×9/33

= -10/11×3/11

= -30/121

RHS = b×a

= 9/33×-10/11

= 3/11×-10/11

= -30/121

LHS=RHS Verified
