a) \(\frac{7}{24}\) + \(\frac{13}{6}\) = \(\frac{7}{24}\) + \(\frac{52}{24}\) = \(\frac{59}{24}\)
b) \(\frac{12}{49}\) - \(\frac{1}{7}\) = \(\frac{12}{49}\) - \(\frac{7}{49}\) = \(\frac{5}{49}\)
c) \(\frac{5}{8}\) x \(\frac{24}{25}\) = \(\frac{120}{200}\) = \(\frac{3}{5}\)
d) \(\frac{38}{21}\) : \(\frac{19}{3}\) = \(\frac{38}{21}\) x \(\frac{3}{19}\) = \(\frac{114}{399}\) = \(\frac{38}{133}\)
