Answer

To add \(4 \frac{2}{8}\) and \(1 \frac{1}{8}\), add the whole numbers to get 5 and the fractions to get \(\frac{3}{8}\), resulting in \(5 \frac{3}{8}\).

Solution

To add the mixed numbers \(4 \frac{2}{8}\) and \(1 \frac{1}{8}\) using equivalent fractions, follow these steps: 1. **Ensure the Fractions Have the Same Denominator:** Both fractions already have the same denominator of 8: \[ \frac{2}{8} \quad \text{and} \quad \frac{1}{8} \] *If they had different denominators, you would convert them to equivalent fractions with a common denominator before proceeding.* 2. **Add the Whole Numbers:** Add the whole number parts of each mixed number: \[ 4 + 1 = 5 \] 3. **Add the Fractional Parts:** Since the denominators are the same, simply add the numerators: \[ \frac{2}{8} + \frac{1}{8} = \frac{2 + 1}{8} = \frac{3}{8} \] 4. **Combine the Sums:** Combine the sum of the whole numbers with the sum of the fractions: \[ 5 + \frac{3}{8} = 5 \frac{3}{8} \] **Final Answer:** \[ 4 \frac{2}{8} + 1 \frac{1}{8} = 5 \frac{3}{8} \]

To simplify the problem, you can express the mixed numbers as improper fractions. Convert \(4 \frac{2}{8}\) to an improper fraction: \(4 \times 8 + 2 = 32 + 2 = 34\), so it becomes \(\frac{34}{8}\). Similarly, convert \(1 \frac{1}{8}\): \(1 \times 8 + 1 = 8 + 1 = 9\), giving \(\frac{9}{8}\). Now, you can add the two fractions, \(\frac{34}{8} + \frac{9}{8} = \frac{43}{8}\). To make your calculations easier, knowing equivalent fractions can help simplify fractions before dealing with addition. For instance, \(\frac{34}{8}\) can be simplified to \(\frac{17}{4}\), which makes it easier to combine with other fractions like \(\frac{9}{8}\). It’s all about finding those common denominators or simplifying first for a smoother math ride!
