Question

1 What properties, the following expressions show?
(i) 2/3+4/5=4/5+2/3
(ii) 1/3×2/3=2/3×1/3
2. If a = 1/2, b = 3/4, verify the following:
(i) a × b = b × a
(ii) a + b = b + a

Answer 1

Step-by-step explanation:

1 (1) commutative property of addition of rational numbers. (a+b = b+a)

(2) commutative property of multiplication of rational numbers . ( a×b = b×a)

2 (1) 1/2 × 3/4 = 3/8

3/4 × 1/2 =3/8

(2) 1/2 + 3/4 = 1+ 6 /2 = 7/2

3/4 +1/2 = 6+1/2 =7/2
