=====================================================

The distributive property is a fundamental concept in mathematics that allows us to simplify complex expressions by distributing a single value across multiple terms. In this article, we will explore how to use the distributive property to simplify an expression involving variables.

What is the Distributive Property?

The distributive property is a mathematical concept that states that for any real numbers a, b, and c, the following equation holds:

a(b + c) = ab + ac

This means that we can distribute a single value (in this case, a) across multiple terms (b and c) to simplify the expression.

Applying the Distributive Property to Variables

Now, let's apply the distributive property to the given expression:

$\frac{1}{4}(16v + 4w) = [?]v + \square w$

To simplify this expression, we need to distribute the $\frac{1}{4}$ across the two terms inside the parentheses.

Step 1: Distribute the $\frac{1}{4}$ across the first term

The first term inside the parentheses is $16v$ . To distribute the $\frac{1}{4}$ across this term, we multiply the $\frac{1}{4}$ by $16v$ :

$\frac{1}{4} \cdot 16v = 4v$

So, the first term becomes $4v$ .

Step 2: Distribute the $\frac{1}{4}$ across the second term

The second term inside the parentheses is $4w$ . To distribute the $\frac{1}{4}$ across this term, we multiply the $\frac{1}{4}$ by $4w$ :

$\frac{1}{4} \cdot 4w = w$

So, the second term becomes $w$ .

Step 3: Combine the simplified terms

Now that we have distributed the $\frac{1}{4}$ across both terms, we can combine the simplified terms:

$4v + w$

Therefore, the simplified expression is:

$4v + w$

Conclusion

In this article, we used the distributive property to simplify an expression involving variables. We applied the distributive property to the given expression, distributing the $\frac{1}{4}$ across the two terms inside the parentheses. By following the steps outlined above, we were able to simplify the expression and arrive at the final answer.
