Answer:
(i) LHS = a × b
= 1/2 × 3/4
= 3/8
RHS = b × a
= 3/4 × 1/2
= 3/8
LHS = RHA
HENCE, PROVED
(ii) LHS = a+b
= 1/2 + 3/4
= 5/4
RHS = b+a
= 3/4 + 1/2
= 5/4
LHS = RHS

Step-by-step explanation:
a = 1/2= b =3/4
(i) a x b = b x a
a× b = 1/2 × 3/4
= 3/8
b× a = 3/4 × 1/2
= 3/8
ii) a + b = b + a
a+ b = 1/2 + 3/4
= (2+3)/4
= 5/ 4
b+ a = 3/4 + 1/2
= ( 3+ 2)/2
= 5/ 4
hence,
a x b = b x a
a + b = b + a ( proved)
hope it helps you friend
