Write the numbers 24, 16, and 36 as the product of two numbers. One is done for you.

Question 1. Show the products of two numbers for 30.
Answer: The number 30 can be written as a product of two numbers in several ways. The pairs are: 10 multiplied by 3, 5 multiplied by 6, 15 multiplied by 2, and 1 multiplied by 30. Finding these pairs helps understand how numbers are built from smaller parts.
In simple words: For the number 30, you can make it by multiplying 10 and 3, or 5 and 6, or 15 and 2, or 1 and 30.

🎯 Exam Tip: When finding factors, always start with 1 and the number itself, then try 2, 3, and so on, to make sure you don't miss any pairs.

Question 2. Show the products of two numbers for 24.
Answer: The number 24 can be expressed as a product of two numbers using the following pairs: 2 multiplied by 12, 3 multiplied by 8, 4 multiplied by 6, and 1 multiplied by 24. These combinations all result in 24.
In simple words: To get 24, you can multiply 2 by 12, 3 by 8, 4 by 6, or 1 by 24.

🎯 Exam Tip: Remember that the order of multiplication does not change the product (e.g., 2 x 12 is the same as 12 x 2), but it's good to list unique pairs.

Question 3. Show the products of two numbers for 16.
Answer: The number 16 can be written as a product of two numbers using these pairs: 2 multiplied by 8, 4 multiplied by 4, 8 multiplied by 2, and 1 multiplied by 16. Each of these pairs gives 16 when multiplied. This shows that a number can have multiple factor pairs.
In simple words: For 16, you can multiply 2 and 8, or 4 and 4, or 8 and 2, or 1 and 16.

🎯 Exam Tip: Don't forget that a number multiplied by itself can also be a factor pair, like 4 x 4 for 16.

Question 4. Show the products of two numbers for 36.
Answer: The number 36 can be shown as a product of two numbers through these combinations: 2 multiplied by 18, 3 multiplied by 12, 4 multiplied by 9, and 6 multiplied by 6. Also, 1 multiplied by 36 is a pair. Identifying all these pairs helps in understanding the factors of a number.
In simple words: You can get 36 by multiplying 2 by 18, 3 by 12, 4 by 9, or 6 by 6. And don't forget 1 by 36.

🎯 Exam Tip: Listing factors in order (e.g., starting with 1, then 2, 3, etc.) helps ensure you find all possible pairs for a number.
