Adding Improper Fractions – Class 4 Maths Practice Worksheet

You can easily add improper fractions by following a clear, step-by-step method. The process depends on whether the fractions have like or unlike denominators.

1. Check the Denominators: If the denominators are the same, simply add the numerators together and keep the denominator.
2. Find a Common Denominator: If the denominators are different, find the Least Common Multiple (LCM) to make them the same.
3. Add the Numerators: Add the new numerators.
4. Simplify the Answer: Simplify the resulting fraction to its lowest terms or convert it into a mixed number if required.

A simple example of an improper fraction is 7/5 (seven-fifths). In this fraction, the numerator 7 is greater than the denominator 5, making its value more than one whole.

• Other common examples include 3/2, which equals 1 ½.
• Another example is 11/4, which equals 2 ¾.
• Even 9/9 is an improper fraction because it equals the whole number 1.

To add improper fractions with different denominators, you must first find a common denominator. This crucial step makes the fractions compatible for addition.

1. Step 1: Find the Least Common Multiple (LCM) of the different denominators.
2. Step 2: Convert each improper fraction into an equivalent fraction using the LCM as the new denominator.
3. Step 3: Add the numerators of the new, equivalent fractions.
4. Step 4: Place the sum of the numerators over the common denominator and simplify the result if possible. For example, to add 5/3 + 7/2, the LCM is 6, so you solve 10/6 + 21/6 = 31/6.

In Class 4, adding fractions involves ensuring the denominators are the same before you combine the numerators. This rule applies to all types of fractions, including proper and improper.

• For Like Denominators: Simply add the numerators and keep the same denominator. Example: 5/4 + 6/4 = 11/4.
• For Unlike Denominators: Find a common denominator, create equivalent fractions, and then add the numerators.
• This fraction addition for grade 4 worksheet provides excellent practice for mastering both scenarios.

The main difference between a proper and an improper fraction lies in the relationship between the numerator and the denominator. This determines if the fraction's value is less than, equal to, or greater than one.

• A proper fraction has a numerator that is smaller than its denominator (e.g., 2/5). Its value is always less than 1.
• An improper fraction has a numerator that is greater than or equal to its denominator (e.g., 5/2 or 4/4). Its value is always 1 or greater.

Yes, this adding improper fractions worksheet comes with a complete answer key. The solutions are provided at the end to help students and parents check their work easily after completing all the fraction addition problems, which is ideal for self-assessment and revision.

This Class 4 maths worksheet is very useful because it offers focused practice on adding improper fractions, a core topic in the Grade 4 syllabus. It helps build both speed and accuracy in calculations.

• It helps students master fraction sums with both like and unlike denominators.
• The printable PDF format is perfect for homework, classroom drills, and holiday practice.
• It strengthens the foundation for more advanced fraction topics like adding mixed numbers.

Yes, it is always a good practice to simplify the final answer after adding improper fractions. Simplifying makes the answer easier to understand and is often a required step in maths problems.

• Simplifying means reducing the fraction to its lowest terms.
• You may also need to convert the final improper fraction into a mixed number (e.g., converting 7/3 to 2 ⅓).
