The TI-30X IIS is a powerful calculator that can be used to enter, evaluate, and manipulate fractions. By following the steps in this guide, you can learn how to use the calculator to perform basic fraction operations.

Simplifying Fractions

To simplify a fraction, you need to find the greatest common factor (GCF) of the numerator and denominator. The GCF is the largest number that can be divided evenly into both the numerator and denominator. Once you have found the GCF, you can divide both the numerator and denominator by it. This will reduce the fraction to its simplest form.

For example, to simplify the fraction 30/60, you would first find the GCF of 30 and 60. The GCF is 10. You would then divide both the numerator and denominator by 10, giving you the simplified fraction 3/6.

Here are the steps to simplify a fraction:

1. Find the GCF of the numerator and denominator.
2. Divide both the numerator and denominator by the GCF.
3. The resulting fraction is in its simplest form.

Adding and Subtracting Fractions

To add or subtract fractions, you need to first make sure that the fractions have the same denominator. If the denominators are not the same, you can find a common denominator by multiplying the denominators of the two fractions.

Once you have a common denominator, you can add or subtract the numerators of the fractions. The resulting numerator will be the numerator of the simplified fraction. The denominator will be the common denominator.

For example, to add 1/2 and 1/3, you would first find a common denominator. The least common multiple of 2 and 3 is 6. You would then multiply each fraction by the appropriate number to get a common denominator of 6.

1/2 * 3 = 3/6
1/3 * 2 = 2/6

You would then add the numerators of the two fractions.

3/6 + 2/6 = 5/6

The resulting fraction is 5/6.

Here are the steps to add or subtract fractions:

1. Make sure that the fractions have the same denominator.
2. Find a common denominator by multiplying the denominators of the two fractions.
3. Multiply each fraction by the appropriate number to get a common denominator.
4. Add or subtract the numerators of the fractions.
5. The resulting numerator will be the numerator of the simplified fraction.
6. The denominator will be the common denominator.

Fractions can be simplified and added or subtracted using a few simple steps. By following these steps, you can easily perform these operations on fractions.
