Work Out $\frac{4}{9} \div \frac{5}{9}$.Give Your Answer As A Fraction In Its Simplest Form.
Introduction
When working with fractions, division can be a bit tricky. However, with a clear understanding of the concept and a step-by-step approach, you can simplify fractions with ease. In this article, we will guide you through the process of working out $\frac{4}{9} \div \frac{5}{9}$ and provide you with a simplified fraction in its simplest form.
Understanding Division of Fractions
To divide fractions, we need to follow a specific rule: to divide by a fraction, we multiply by its reciprocal. The reciprocal of a fraction is obtained by swapping its numerator and denominator. For example, the reciprocal of $\frac{a}{b}$ is $\frac{b}{a}$.
Step 1: Identify the Dividend and Divisor
In the given problem, $\frac{4}{9}$ is the dividend, and $\frac{5}{9}$ is the divisor.
Step 2: Find the Reciprocal of the Divisor
To divide by $\frac{5}{9}$, we need to find its reciprocal, which is $\frac{9}{5}$.
Step 3: Multiply the Dividend by the Reciprocal of the Divisor
Now, we multiply the dividend $\frac{4}{9}$ by the reciprocal of the divisor $\frac{9}{5}$.
Step 4: Simplify the Fraction
We can simplify the fraction by canceling out common factors in the numerator and denominator.
Conclusion
By following the steps outlined above, we have successfully simplified the fraction $\frac4}{9} \div \frac{5}{9}$ to its simplest form{5}$.
