What is \( 3 \cdot 4 \cdot 5 \)?

What is \( 3 \cdot 4 \cdot 5 \)?

• A. 60
• B. 70
• C. 50
• D. 40

Answer: (A)

To find the product of the numbers \( 3 \), \( 4 \), and \( 5 \), you can multiply them together step by step. First, you can multiply \( 3 \) and \( 4 \): \[ 3 \cdot 4 = 12 \] Next, take the result \( 12 \) and multiply it by \( 5 \): \[ 12 \cdot 5 = 60 \] Thus, the value of \( 3 \cdot 4 \cdot 5 \) is \( 60 \), making it the correct answer. This process demonstrates the associative property of multiplication, where the grouping of the numbers can be rearranged without changing the result. Hence, you can also first multiply \( 4 \cdot 5 \) to get \( 20 \), and then multiply that result by \( 3 \): \[ 3 \cdot (4 \cdot 5) = 3 \cdot 20 = 60 \] This confirms that \( 3 \cdot 4 \cdot 5 \) consistently equals \( 60 \), validating the answer provided.

To find the product of the numbers ( 3 ), ( 4 ), and ( 5 ), you can multiply them together step by step.

First, you can multiply ( 3 ) and ( 4 ):

[

3 \cdot 4 = 12

]

Next, take the result ( 12 ) and multiply it by ( 5 ):

[

12 \cdot 5 = 60

]

Thus, the value of ( 3 \cdot 4 \cdot 5 ) is ( 60 ), making it the correct answer.

This process demonstrates the associative property of multiplication, where the grouping of the numbers can be rearranged without changing the result. Hence, you can also first multiply ( 4 \cdot 5 ) to get ( 20 ), and then multiply that result by ( 3 ):

[

3 \cdot (4 \cdot 5) = 3 \cdot 20 = 60

]

This confirms that ( 3 \cdot 4 \cdot 5 ) consistently equals ( 60 ), validating the answer provided.
