Explanation: প্রয়োজনীয় চিনির amount \(=\left(\frac{3}{8}+\frac{3}{5}\right)\text{ cup}=\frac{15+24}{40} \text{ cup} = \frac{39}{40}\) cup. যেহেতু \(\frac{15}{16}\) cup, \(\frac{39}{40}\) cup অপেক্ষা ছোট। অতিরিক্ত চিনি প্রয়োজন \(=\left(\frac{39}{40}-\frac{15}{16}\right) \text{ cup} = \frac{78-75}{80} = \frac{3}{80}\) cup.
