Question

I need some help with these..​

Answer 1

Step-by-step explanation:

A) Commutative property of multiplication

a x b = b x a

B) Associative property of multiplication

( a x b ) x c = a x ( b x c )

C) Multiplicative inverse ( Reciprocal )

a/b will convert into b/a

For example : Multiplicative inverse of 1/2 is 2/1.

D) Multiplicative identity (1)

1 is the Multiplicative identity.

Because,

Any number x 1 = 1

Answer 2

In all Examples we will take a = 5, b= 6 and c = 7

a) Commutativity property of multiplication :- a × b = b × a

Example : - 5 × 6 = 6 × 5 = 30

b) Associativity property of multiplication :- (a × b) × c= a × (b × c) = (a × c) × b

Example : - (5 × 6) × 7 = (5 × 6) × 7 = (5 × 7) × 6 = 210

c) Multiplicative inverse :- a × 1/a = 1

Example : - 5 × 1/5 = 1

d) Additive identity : - a + 0 = a

Example : - 5 + 0 = 5
