1) \(3k + \frac{1}{5}k = \frac{15}{5}k + \frac{1}{5}k = \frac{16}{5}k\) 2) \(\frac{24}{5}k - 1k = \frac{24}{5}k - \frac{5}{5}k = \frac{19}{5}k\) 3) \(\frac{4m}{9} + \frac{1}{2}m + \frac{1}{18}m = \frac{8m}{18} + \frac{9m}{18} + \frac{1m}{18} = \frac{18m}{18} = m\) 4) \(\frac{5h}{6} - \frac{1h}{12} + \frac{13h}{18} = \frac{30h}{36} - \frac{3h}{36} + \frac{26h}{36} = \frac{53h}{36}\) 5) \(\frac{17h}{21} - \frac{1h}{18} + \frac{3h}{7} = \frac{612h}{756} - \frac{42h}{756} + \frac{324h}{756} = \frac{894h}{756} = \frac{149h}{126}\)
