Let's fill in the table with the common fractions, decimal fractions, and percentages based on your provided values. Here we go! For \(a)\) \( \frac{3}{8} \), when converted to a decimal, it's 0.375. To express it as a percentage, simply multiply the decimal by 100, resulting in 37.5%. For \(b)\) \( \frac{125}{825} \), simplifying this gives \( \frac{5}{33} \). Dividing gives approximately 0.1515, and as a percentage, it's about 15.15%. For \(c)\) \( \frac{17}{8} \), this improper fraction equals 2.125 as a decimal, which is also 212.5% when converted. For \(d)\) \( \frac{2}{3} \), this equals approximately 0.6667 in decimal, which corresponds to 66.67% when multiplied by 100. For \(e)\) \( \frac{12}{100} \) is already in fraction form, so it's 0.12 as a decimal and 12% in percentage form. For \(f)\) with decimal value 0.65, converting this back gives \( \frac{65}{100} \) or simplified to \( \frac{13}{20} \). As a percentage, it's 65%. For \(g)\) with decimal value 0.244, you can express this as \( \frac{244}{1000} \), which doesn’t simplify well. As a percentage, it’s 24.4%. For \(h)\) with decimal value 1.5, this translates to \( \frac{3}{2} \) as a common fraction and 150% when represented as a percentage. For \(i)\) with decimal value 0.35, you can represent this as \( \frac{35}{100} \) or \( \frac{7}{20} \) when simplified. Converted to a percentage, it's 35%. Now, the completed table would look like this: \begin{tabular}{|l|c|c|c|}\hline & Common fraction & Decimal fraction & Percentage \\ \hline a) & \( \frac{3}{8} \) & 0.375 & 37.5\% \\ \hline b) & \( \frac{5}{33} \) & 0.1515 & 15.15\% \\ \hline c) & \( \frac{17}{8} \) & 2.125 & 212.5\% \\ \hline d) & \( \frac{2}{3} \) & 0.6667 & 66.67\% \\ \hline e) & \( \frac{12}{100} \) & 0.12 & 12\% \\ \hline f) & \( \frac{13}{20} \) & 0.65 & 65\% \\ \hline g) & \( \frac{244}{1000} \) & 0.244 & 24.4\% \\ \hline h) & \( \frac{3}{2} \) & 1.5 & 150\% \\ \hline i) & \( \frac{7}{20} \) & 0.35 & 35\% \\ \hline \end{tabular}
