What are Mixed and Improper Fractions?

Before we delve into the worksheet, let's clarify the definitions of mixed and improper fractions.

• Mixed Fractions: A mixed fraction combines a whole number and a proper fraction. A proper fraction is a fraction where the numerator (the top number) is smaller than the denominator (the bottom number). For example, 2 ¾ is a mixed fraction. It represents two whole units and three-quarters of another unit.

• Improper Fractions: An improper fraction is a fraction where the numerator is greater than or equal to the denominator. For example, 11/4 is an improper fraction. It represents more than one whole unit.

Understanding the difference between these two types of fractions is the first step towards mastering them. The ability to convert between them is crucial for solving various mathematical problems.

Converting Between Mixed and Improper Fractions

The ability to seamlessly switch between mixed and improper fractions is vital for simplifying expressions and solving equations. Here's a step-by-step guide for both conversions:

Converting a Mixed Fraction to an Improper Fraction

1. Multiply the whole number by the denominator: This gives you the total number of parts in the whole numbers.

2. Add the numerator: This adds the additional fractional parts to the total.

3. Keep the same denominator: The denominator remains unchanged, representing the size of each part.

Example: Convert 3 ½ to an improper fraction.

1. Multiply the whole number (3) by the denominator (2): 3 * 2 = 6
2. Add the numerator (1): 6 + 1 = 7
3. Keep the same denominator (2): The improper fraction is 7/2.

Converting an Improper Fraction to a Mixed Fraction

1. Divide the numerator by the denominator: This gives you the whole number part of the mixed fraction.

2. The remainder becomes the numerator: The remainder from the division forms the numerator of the proper fraction.

3. Keep the same denominator: The denominator remains the same as in the original improper fraction.

Example: Convert 17/5 to a mixed fraction.

1. Divide the numerator (17) by the denominator (5): 17 ÷ 5 = 3 with a remainder of 2.
2. The remainder (2) becomes the new numerator.
3. Keep the same denominator (5): The mixed fraction is 3 2/5.

Simplifying Fractions

Simplifying, or reducing, fractions means expressing them in their lowest terms. This involves finding the greatest common divisor (GCD) of the numerator and the denominator and dividing both by it.

Example: Simplify the fraction 12/18.

1. Find the GCD of 12 and 18. The GCD is 6.
2. Divide both the numerator and the denominator by 6: 12 ÷ 6 = 2 and 18 ÷ 6 = 3.
3. The simplified fraction is 2/3.
