(55 + 36) × 26 = (55 x 26) + (36 x 26) Identity property of multiplication Commutative property of multiplication Associative property of multiplication Distributive property of multiplication over addition c, 55 × 1 = 1 × 55 = 55 Identity property of multiplication Commutative property of multiplication Associative property of multiplication Distributive property of multiplication over addition

Solution

a) As per associative property of multiplication :

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

So, associative property of multiplication

b) the distributive property of multiplication over addition can be used when you multiply a number by a sum.

eg : 3( 10 +2) = 3(10) + 3(2)

distributive property of multiplication over addition is being used

c) The identity property for multiplication tells us that the number 1 multiplied times any number gives the number itself.
