Introduction

In mathematics, factor pairs are essential in understanding the properties of numbers and their relationships. A factor pair of a number is a pair of numbers that can be multiplied together to get the original number. For instance, 6 and 9 are a factor pair of 54 because $6 \times 9 = 54$ . Breaking apart the factors of a number can help us find other factorizations and understand the underlying structure of the number. In this article, we will explore how to break apart the factor 9 in the expression $54 = 6 \times 9$ .

Understanding Factor Pairs

A factor pair of a number is a pair of numbers that can be multiplied together to get the original number. For example, the factor pairs of 12 are (1, 12), (2, 6), and (3, 4). Factor pairs are essential in mathematics as they help us understand the properties of numbers and their relationships.

Breaking Apart Factors

Breaking apart factors is a technique used to find other factorizations of a number. It involves expressing one of the factors as a product of smaller numbers. For instance, in the expression $54 = 6 \times 9$ , we can break apart the factor 9 by expressing it as a product of smaller numbers.

Breaking Apart the Factor 9

To break apart the factor 9 in the expression $54 = 6 \times 9$ , we need to find two numbers that can be multiplied together to get 9. The two numbers that satisfy this condition are 2 and 3, as $2 \times 3 = 6$ . Therefore, we can break apart the factor 9 as follows:

54 = 6 \times (2 \times 3)

This expression correctly shows breaking apart the factor 9 in the expression $54 = 6 \times 9$ .

Conclusion

In conclusion, breaking apart factors is a technique used to find other factorizations of a number. By expressing one of the factors as a product of smaller numbers, we can find new factorizations and understand the underlying structure of the number. In this article, we explored how to break apart the factor 9 in the expression $54 = 6 \times 9$ and found that the correct expression is $54 = 6 \times (2 \times 3)$ .

Example 1: Breaking Apart the Factor 12

Let's consider the expression $12 = 3 \times 4$ . We can break apart the factor 4 by expressing it as a product of smaller numbers. The two numbers that satisfy this condition are 2 and 2, as $2 \times 2 = 4$ . Therefore, we can break apart the factor 4 as follows:

12 = 3 \times (2 \times 2)

This expression correctly shows breaking apart the factor 4 in the expression $12 = 3 \times 4$ .

Example 2: Breaking Apart the Factor 15

Let's consider the expression $15 = 3 \times 5$ . We can break apart the factor 5 by expressing it as a product of smaller numbers. The two numbers that satisfy this condition are 1 and 5, as $1 \times 5 = 5$ . Therefore, we can break apart the factor 5 as follows:

15 = 3 \times (1 \times 5)

This expression correctly shows breaking apart the factor 5 in the expression $15 = 3 \times 5$ .
