Adding Fractions: The Smile and Kiss Method
The smile and kiss method is an effective technique for adding fractions with different denominators. This page outlines the four essential steps to successfully implement this method.
Definition: The smile and kiss method is a systematic approach to adding fractions by creating a common denominator and then performing the addition.
Step 1: Multiply the denominators
In this step, you multiply the denominators of the fractions you're adding. This creates a common denominator for both fractions.
Step 2: Cross-multiply numerators and denominators
Next, multiply the numerator of each fraction by the denominator of the other fraction. This step is crucial for maintaining the proportional value of each fraction while giving them a common denominator.
Step 3: Add the fractions
Now that both fractions have the same denominator, you can add the numerators together. The denominator remains the same as the one calculated in Step 1.
Step 4: Simplify if possible
After adding the fractions, check if the resulting fraction can be simplified by finding common factors in the numerator and denominator.
Example: The image shows an example of adding 3/2 and 1/4 using the smile and kiss method. The steps are clearly illustrated, demonstrating how to arrive at the final answer of 7/4.
Highlight: This method is particularly useful for students learning how to add fractions with different denominators and can be extended to adding 3 fractions with different denominators or more.
The smile and kiss method provides a structured approach to fraction addition, making it easier for students to understand and apply. It's an excellent tool for those looking to improve their skills in adding and simplifying fractions.
