Question

Q1. Name the property used in the following
a) 15 x (21 x 8) = (15 x 21) x 8
b) 106 x 42 = 42 x 106
c) 154 + 0 = 154
d) 42 x 58 is a whole number
e) 65 x*(100 + 8) = (65 x 100) + ( 65 x 8)
f) 189 x 1 = 189​

Answer 1

a) 15 x (21 x 8) = (15 x 21) x 8

Associative Property of Multiplication

b) 106 x 42 = 42 x 106

Commutative property

c) 154 + 0 = 154

Additive identify

d) 42 x 58 is a whole number

Closer property

e) 65 x*(100 + 8) = (65 x 100) + ( 65 x 8)

Distributive property of multiplication over addition

f) 189 x 1 = 189

Multiplicative Identity
