Solution

$(i) \frac{2}{3} - \frac{3}{5} = \frac{10}{15} - \frac{9}{15} = \frac{10 - 9}{15} = \frac{1}{15} (ii) \frac{- 4}{7} - \frac{2}{- 3} = \frac{- 12}{21} - \frac{- 14}{21} = \frac{(- 12) - (- 14)}{21} = \frac{- 12 + 14}{21} = \frac{2}{21} (iii) \frac{4}{7} - \frac{- 5}{- 7} = \frac{4 - 5}{7} = \frac{- 1}{7} (iv) - 2 - \frac{5}{9} = \frac{- 18}{9} - \frac{5}{9} = \frac{- 18 - 5}{9} = \frac{- 23}{9} (v) \frac{- 3}{- 8} - \frac{- 2}{7} = \frac{21}{56} - \frac{- 16}{56} = \frac{21 - (- 16)}{56} = \frac{21 + 16}{56} = \frac{37}{56} (vi) \frac{- 4}{13} - \frac{- 5}{26} = \frac{- 8}{26} - \frac{- 5}{26} = \frac{- 8 - (- 5)}{26} = \frac{- 8 + 5}{26} = \frac{- 3}{26} (vii) \frac{- 5}{14} - \frac{- 2}{7} = \frac{- 5}{14} - \frac{- 4}{14} = \frac{- 5 - (- 4)}{14} = \frac{- 5 + 4}{14} = \frac{- 1}{14} (viii) \frac{13}{15} - \frac{12}{25} = \frac{65}{75} - \frac{36}{75} = \frac{65 - 36}{75} = \frac{29}{75} (ix) \frac{- 6}{13} - \frac{- 7}{13} = \frac{- 6 - (- 7)}{13} = \frac{- 6 + 7}{13} = \frac{1}{13} (x) \frac{7}{24} - \frac{19}{36} = \frac{21}{72} - \frac{38}{72} = \frac{21 - 38}{72} = \frac{- 17}{72} (xi) \frac{5}{63} - \frac{- 8}{21} = \frac{5}{63} - \frac{- 24}{63} = \frac{5 - (- 24)}{63} = \frac{5 + 24}{63} = \frac{29}{63}$
