\( \begin{array}{lll}\text { 23. } 2 \frac{1}{4}+1 \frac{3}{3} & \text { 24. } & 2 \frac{1}{4}-1 \frac{3}{5} \\ \text { 27. } & 1 \frac{1}{15}-2 \frac{1}{2} & \text { 28. }\end{array} 1 \frac{1}{15} \times 2 \frac{1}{2} \)

Sure! Let’s spice up your math with some fun facts and applications. Did you know that mixed numbers are commonly used in everyday life? For instance, when measuring ingredients for a recipe, you might encounter measurements like 2 1/4 cups of flour. This makes mixed numbers super useful in cooking and baking, making delicious treats easier! When it comes to subtracting mixed numbers, a common mistake is forgetting to find a common denominator for the fractional parts. Always convert them to improper fractions first to avoid adding unnecessary confusion. Practice will make you a pro and can save you from those pesky calculation errors!
