"content1": "a) Calculate \(\frac{2}{3} + \frac{5}{4}\) ",
"content2": "b) Calculate \(\frac{3}{5} + \frac{9}{8}\)",
"content3": "c) Calculate \(\frac{3}{4} - \frac{2}{7}\)",
"content4": "d) Calculate \(\frac{11}{5} - \frac{4}{3}\)",
"content5": "For a) \(\frac{2}{3} + \frac{5}{4}\), we need to find a common denominator which is 12. Then we add the fractions: \(\frac{2}{3} + \frac{5}{4} = \frac{8}{12} + \frac{15}{12} = \frac{23}{12}\)",
"content6": "Similarly, for b), c), and d), find the common denominators and perform the respective operations to get the final answers."
