Question

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the tion bar(s). Here is a multiplication sentence: 1 × 3 = 3. Use the commutative property of multiplication to write a related multiplication sentence.

a) 3 × 1 = 3

b) 1 × 3 = 3

c) 3 × 3 = 9

d) 1 × 1 = 1

Answer 1

Using the commutative property of multiplication, the related multiplication sentence for 1 × 3 = 3 is 3 × 1 = 3. The correct answer is option (a).

Step-by-step explanation:

The student is asked to apply the commutative property of multiplication to write a related multiplication sentence based on the given example 1 × 3 = 3. According to the commutative property, the order of factors in a multiplication sentence does not affect the product. Therefore, if we swap the factors, the related multiplication sentence using the commutative property would be: 3 × 1 = 3.

From the provided options:

• a) 3 × 1 = 3 (Correct, applies the commutative property)
• b) 1 × 3 = 3 (Same as initial sentence provided)
• c) 3 × 3 = 9 (Incorrect, changes the factors)
• d) 1 × 1 = 1 (Incorrect, changes the factors)

The correct answer is therefore (a) 3 × 1 = 3 which reflects the commutative property.
