Subtract Unlike Fractions Worksheets Made Easy

Understanding the Concept of Subtracting Unlike Fractions

When it comes to fractions, subtracting unlike fractions can be a bit more complex than adding them. Unlike fractions are those that have different denominators, making it necessary to find a common denominator before performing the subtraction operation.

What is the Process of Subtracting Unlike Fractions?

To subtract unlike fractions, you need to follow a step-by-step process that involves finding the least common multiple (LCM) of the denominators, converting each fraction to an equivalent fraction with the LCM as the denominator, and then subtracting the numerators.

Step 1: Find the Least Common Multiple (LCM)

To find the LCM, you can list the multiples of each denominator and identify the smallest multiple they have in common. For example, if you have two fractions with denominators of 6 and 8, the multiples of 6 are 6, 12, 18, 24,… and the multiples of 8 are 8, 16, 24, 32,…. Therefore, the LCM of 6 and 8 is 24.

Tips for Finding the LCM:

• List the multiples of each denominator.
• Identify the smallest multiple they have in common.
• Use a calculator or online tool to find the LCM if you’re struggling to find it manually.

Step 2: Convert Each Fraction to an Equivalent Fraction with the LCM as the Denominator

Once you have the LCM, you need to convert each fraction to an equivalent fraction with the LCM as the denominator. To do this, multiply the numerator and denominator of each fraction by the necessary multiplier.

Example:

If you have two fractions with denominators of 6 and 8, and the LCM is 24, you would convert each fraction as follows:

• ¹⁄₆ = (1 x 4) / (6 x 4) = ⁴⁄₂₄
• ¹⁄₈ = (1 x 3) / (8 x 3) = ³⁄₂₄

Step 3: Subtract the Numerators

Now that you have equivalent fractions with the same denominator, you can subtract the numerators.

Example:

If you have two fractions with numerators of 4 and 3, and the same denominator of 24, you would subtract the numerators as follows:

⁴⁄₂₄ - ³⁄₂₄ = (4 - 3)/24 = ¹⁄₂₄

Tips for Subtracting Numerators:

• Make sure the fractions have the same denominator.
• Subtract the numerators.
• Write the result as a fraction with the same denominator.
