Fractions

A fraction represents a part of a whole or a part of a group. It consists of a numerator (the top number) and a denominator (the bottom number). The numerator represents the number of parts we have, and the denominator represents the total number of parts that make up the whole or the group.

Types of Fractions

There are different types of fractions:

1. Proper Fraction: A fraction where the numerator is less than the denominator, e.g., 3/4.
2. Improper Fraction: A fraction where the numerator is greater than or equal to the denominator, e.g., 7/4.
3. Mixed Number: A whole number combined with a fraction, e.g., 1 3/4.
4. Equivalent Fractions: Fractions that represent the same value, e.g., 1/2 and 2/4.

Operations with Fractions

There are four basic operations that can be performed with fractions:

1. Addition: To add fractions, make sure the denominators are the same, then add the numerators together and keep the denominator the same, e.g., 1/3 + 1/6 = (2/6) + (1/6) = 3/6 = 1/2.
2. Subtraction: To subtract fractions, make sure the denominators are the same, then subtract the numerators and keep the denominator the same, e.g., 5/8 - 3/8 = 2/8 = 1/4.
3. Multiplication: To multiply fractions, simply multiply the numerators together to get the new numerator and the denominators together to get the new denominator, e.g., 2/3 * 3/4 = (2*3)/(3*4) = 6/12 = 1/2.
4. Division: To divide fractions, multiply the first fraction by the reciprocal of the second fraction, e.g., 2/3 ÷ 4/5 = 2/3 * 5/4 = (2*5)/(3*4) = 10/12 = 5/6.

Comparing Fractions

When comparing fractions, you can use the following methods:

• Common Denominator: Make the denominators the same, then compare the numerators.
• Cross-Multiplication: Multiply the numerator of the first fraction by the denominator of the second fraction and compare it with the product of the numerator of the second fraction and the denominator of the first fraction.

Practice Problems

Now that you understand fractions, try solving the following practice problems:

1. Simplify the fraction 10/15.
2. Add the fractions 1/4 and 1/3.
3. Multiply the fractions 2/5 and 3/8.
4. Compare the fractions 2/3 and 3/4 using a common denominator.
