Question

13.Commutativity under multiplication is shown by
(1 Point)
3 + 49 + 50 = 3 + 50 +49
3 x 49 x 20 = 3 x 20 x 49
3 x ( 49 + 50) = 3 x ( 50 + 49)
(3 x 49) x 20 = 3 x (49 x 20)​

Answer 1

Here is your answer. Commutative property under addition The sum of two whole numbers is the same, no matter in which order they are added. a+b = b+a Commutative property under multiplication : The product of two whole numbers is the same, no matter in which order they are multiplied axb = bxa

Subtraction & division are not Commutative for whole numbers. Distributivity of multiplication over addition : The product of whole numbers with the sum of the other whole numbers is equal to the sum of the products of the whole number with other two whole numbers. a(b+c) = axb axc (i) 425 x 136 = 425 x (6 + 30 + 100) Distributivity of multiplication over addition (ii) 2 x 49 x 50 = 2 x 50 x 49 Commutativity under multiplication (iii) 80 + 2005 + 20 = 80 +20 + 2005 (b) Commutativity under addition
