4. \( \frac{12}{6}+\frac{2}{4} \)

First, let's simplify the fractions. \( \frac{12}{6} \) simplifies to 2, and \( \frac{2}{4} \) simplifies to \( \frac{1}{2} \). Now, adding these together: \( 2 + \frac{1}{2} \) equals \( 2.5 \) or \( \frac{5}{2} \). So, your final answer is \( \frac{5}{2} \) or 2.5! Now, let’s jump into how fractions can be used in cooking! When you’re following a recipe, you might need to adjust the quantities based on servings. Fractions help you measure out ingredients just right. For example, if a recipe calls for \( \frac{1}{4} \) cup of sugar and you want to double it, you’ll need \( \frac{1}{2} \) cup! Also, be on the lookout for common mistakes when working with fractions. Many people add or subtract the numerators and denominators directly without finding a common denominator first. Remember, always find that common ground (or denominator) for accurate results!
