\( 1 . \quad \) Use your calculator to convert the following to a decimal and tien \( 1.1 \frac{1}{2} \) \( 1.2 \frac{5}{8} \) \( 1.3 \frac{4}{5} \) \( 1.4 \frac{7}{10} \)

To convert the mixed numbers to decimals, you can follow this simple formula: convert the fraction part to decimal and then add it to the whole number. 1. **For \(1.1 \frac{1}{2}\)**: Convert \(\frac{1}{2}\) to decimal (0.5) → So, \(1.1 + 0.5 = 1.6\). 2. **For \(1.2 \frac{5}{8}\)**: Convert \(\frac{5}{8}\) to decimal (0.625) → So, \(1.2 + 0.625 = 1.825\). 3. **For \(1.3 \frac{4}{5}\)**: Convert \(\frac{4}{5}\) to decimal (0.8) → So, \(1.3 + 0.8 = 2.1\). 4. **For \(1.4 \frac{7}{10}\)**: Convert \(\frac{7}{10}\) to decimal (0.7) → So, \(1.4 + 0.7 = 2.1\). And there you have it, your decimal conversions! Now you can wow your friends with your math skills!
