K3. Which of the following statements show(s) the distributive property of multiplication of integers?

(a) [tex]2 \times 6=6 \times 2[/tex]

(b) [tex](2 \times 6)+(2 \times 3)=2 \times(6+3)[/tex]

(c) [tex]2 \times 1=2[/tex]

(d) [tex]3 \times(1+2)=(3 \times 1)+(3 \times 2)[/tex]

(e) [tex]3 \times(1 \times 2)=(3 \times 1) \times 2[/tex]

(f) [tex]1 \times 3=3[/tex]



Answer :

To solve this question, we need to identify which of the given statements represent the distributive property of multiplication. The distributive property states that the multiplication of a number by a sum is equal to the sum of the individual products of the addends and the number. In algebraic terms, this is described as:

[tex]\[ a \times (b + c) = (a \times b) + (a \times c) \][/tex]

Now, let's evaluate each option:

(a) [tex]\( 2 \times 6 = 6 \times 2 \)[/tex]
- This is the commutative property of multiplication, which states that the order of the factors does not change the product.

(b) [tex]\( (2 \times 6) + (2 \times 3) = 2 \times (6 + 3) \)[/tex]
- This correctly exemplifies the distributive property. It shows how multiplying 2 by the sum of 6 and 3 is the same as multiplying 2 by 6 and 2 by 3, then adding the results.

(c) [tex]\( 2 \times 1 = 2 \)[/tex]
- This is the multiplicative identity property, which states that any number multiplied by 1 is itself.

(d) [tex]\( 3 \times (1 + 2) = (3 \times 1) + (3 \times 2) \)[/tex]
- This illustrates the distributive property. It shows a number (3) distributed over the sum (1 + 2).

(e) [tex]\( 3 \times (1 \times 2) = (3 \times 1) \times 2 \)[/tex]
- This is the associative property of multiplication, which shows that the way numbers are grouped in multiplication does not change the product.

(f) [tex]\( 1 \times 3 = 3 \)[/tex]
- This again is the multiplicative identity property.

The statements that show the distributive property are therefore:

(b) [tex]\( (2 \times 6) + (2 \times 3) = 2 \times (6 + 3) \)[/tex]

(d) [tex]\( 3 \times (1 + 2) = (3 \times 1) + (3 \times 2) \)[/tex]

Thus, the correct indices for the distributive property of multiplication are [tex]\([2, 4]\)[/tex].
