Question

let A B and C be three rational numbers where a = 2/3, B = 4.5 and c = -5/6 verify associative property of addition and multiplication​

Answer 1

Answer:

19/30

Step-by-step explanation:

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

(2/3+4/5)+(-5/6)=2/3+ (4/5+(-5/6)

22/15+(-5/6)=2/3+(-1/30)

19/30=19/30

Answer 2

Answer:

a, b, c be the three rational numbers where a= 2 /4, b = 3 /5 a b and c = - 5 /6

Verify: (i) a + (b + c) = (a + b) +c (Associative property of addition)

(ii) a × (b × c) = (a × b) × c (Associative property of multiplication
