Introduction

When dealing with fractions, simplifying them is an essential skill to master. It helps in making calculations easier and more efficient. In this article, we will focus on simplifying the expression $\frac{1}{100}$ . We will explore the concept of simplifying fractions, the rules involved, and provide step-by-step examples to help you understand the process.

What is Simplifying a Fraction?

Simplifying a fraction involves expressing it in its simplest form, which means reducing it to its lowest terms. This is done by dividing both the numerator and the denominator by their greatest common divisor (GCD). The GCD is the largest number that divides both the numerator and the denominator without leaving a remainder.

Rules for Simplifying Fractions

There are two main rules to follow when simplifying fractions:

Divide both the numerator and the denominator by their GCD: This is the most common method used to simplify fractions. By dividing both the numerator and the denominator by their GCD, you can reduce the fraction to its simplest form.
Cancel out common factors: If there are any common factors between the numerator and the denominator, you can cancel them out to simplify the fraction.

Simplifying $\frac{1}{100}$

To simplify the expression $\frac{1}{100}$ , we need to find the GCD of 1 and 100. The GCD of 1 and 100 is 1, since 1 is the only number that divides both 1 and 100 without leaving a remainder.

Since the GCD is 1, we cannot simplify the fraction further. Therefore, the simplified form of $\frac{1}{100}$ is still $\frac{1}{100}$ .

Example 1: Simplifying a Fraction with a Common Factor

Let's consider the fraction $\frac{6}{12}$ . To simplify this fraction, we need to find the GCD of 6 and 12. The GCD of 6 and 12 is 6, since 6 is the largest number that divides both 6 and 12 without leaving a remainder.

To simplify the fraction, we divide both the numerator and the denominator by their GCD, which is 6. This gives us:

\frac{6}{12} = \frac{6 \div 6}{12 \div 6} = \frac{1}{2}

Therefore, the simplified form of $\frac{6}{12}$ is $\frac{1}{2}$ .

Example 2: Simplifying a Fraction with a Common Factor

Let's consider the fraction $\frac{9}{18}$ . To simplify this fraction, we need to find the GCD of 9 and 18. The GCD of 9 and 18 is 9, since 9 is the largest number that divides both 9 and 18 without leaving a remainder.

To simplify the fraction, we divide both the numerator and the denominator by their GCD, which is 9. This gives us:

\frac{9}{18} = \frac{9 \div 9}{18 \div 9} = \frac{1}{2}

Therefore, the simplified form of $\frac{9}{18}$ is $\frac{1}{2}$ .

Conclusion

Simplifying fractions is an essential skill to master in mathematics. By understanding the rules involved and following the steps outlined in this article, you can simplify fractions with ease. Remember to find the GCD of the numerator and the denominator, and then divide both by their GCD to simplify the fraction. With practice, you will become proficient in simplifying fractions and be able to tackle more complex problems with confidence.
