Introduction

In mathematics, division is a fundamental operation that allows us to find the quotient of two numbers. When we divide one number by another, we are essentially asking how many times the divisor fits into the dividend. In this article, we will evaluate the expression $$x \div y$$ for $$x = 8$$ and $$y = 16$$. We will break down the steps involved in simplifying this expression and provide a clear understanding of the concept of division.

Understanding the Expression

The given expression is $$x \div y$$, where $$x = 8$$ and $$y = 16$$. To evaluate this expression, we need to find the quotient of $$x$$ and $$y$$. In other words, we need to determine how many times $$y$$ fits into $$x$$.

The Concept of Division

Division is the inverse operation of multiplication. When we multiply two numbers, we are essentially adding a number a certain number of times. For example, $$3 \times 4 = 12$$ means that we are adding $$3$$ together $$4$$ times. On the other hand, when we divide two numbers, we are essentially asking how many times the divisor fits into the dividend.

Evaluating the Expression

To evaluate the expression $$x \div y$$, we need to divide $$x$$ by $$y$$. In this case, we need to divide $$8$$ by $$16$$. To do this, we can use the following steps:

Check if the divisor is zero: Before we start dividing, we need to check if the divisor is zero. If the divisor is zero, then the expression is undefined.
Check if the dividend is zero: We also need to check if the dividend is zero. If the dividend is zero, then the expression is zero.
Divide the dividend by the divisor: If the divisor is not zero and the dividend is not zero, then we can proceed with the division. To do this, we need to divide the dividend by the divisor.

Simplifying the Expression

Now that we have understood the concept of division and evaluated the expression, we can simplify it. To simplify the expression $$x \div y$$, we need to find the quotient of $$x$$ and $$y$$. In this case, we need to find the quotient of $$8$$ and $$16$$.

The Quotient

The quotient of $$8$$ and $$16$$ is $$0.5$$. This means that $$16$$ fits into $$8$$ half a time.

Conclusion

In this article, we evaluated the expression $$x \div y$$ for $$x = 8$$ and $$y = 16$$. We broke down the steps involved in simplifying this expression and provided a clear understanding of the concept of division. We also simplified the expression and found the quotient of $$8$$ and $$16$$, which is $$0.5$$. We hope that this article has provided a clear understanding of the concept of division and how to evaluate and simplify expressions involving division.
