$Not inverting the fraction$

Introduction

In mathematics, division is an essential operation that involves finding the quotient of two numbers. When it comes to fractions, division can be a bit more complex, but with the right approach, it can be simplified. In this article, we will focus on dividing and simplifying the given fraction: $\frac{8}{9} \div 2$ . We will break down the process into manageable steps and provide a clear explanation of each step.

Understanding the Problem

The given problem involves dividing the fraction $\frac{8}{9}$ by 2. To simplify this expression, we need to understand the concept of dividing fractions. When we divide a fraction by a whole number, we can multiply the fraction by the reciprocal of the whole number. In this case, the reciprocal of 2 is $\frac{1}{2}$ .

Step 1: Invert and Multiply

To divide the fraction $\frac{8}{9}$ by 2, we can multiply the fraction by the reciprocal of 2, which is $\frac{1}{2}$ . This is based on the rule that division is the same as multiplying by the reciprocal.

$\frac{8}{9} \div 2 = \frac{8}{9} \times \frac{1}{2}$

Step 2: Multiply the Numerators and Denominators

Now that we have the expression in the form of a multiplication, we can multiply the numerators and denominators separately.

$\frac{8}{9} \times \frac{1}{2} = \frac{8 \times 1}{9 \times 2}$

Step 3: Simplify the Expression

To simplify the expression, we can multiply the numbers in the numerator and denominator.

$\frac{8 \times 1}{9 \times 2} = \frac{8}{18}$

Step 4: Reduce the Fraction

The fraction $\frac{8}{18}$ can be reduced by dividing both the numerator and denominator by their greatest common divisor (GCD). The GCD of 8 and 18 is 2.

$\frac{8}{18} = \frac{8 \div 2}{18 \div 2} = \frac{4}{9}$

Conclusion

In conclusion, dividing and simplifying the given fraction $\frac{8}{9} \div 2$ involves inverting and multiplying the fraction by the reciprocal of 2. We then multiply the numerators and denominators separately and simplify the expression by reducing the fraction. The final result is $\frac{4}{9}$ .
