  • [tex]1 \frac{4}{5} + 1 \frac{3}{4} - 1 \frac{2}{3} \\ = \frac{9}{5} + \frac{7}{4} - \frac{5}{3} \\ = \frac{36}{20} + \frac{35}{20} - \frac{5}{3} \\ = \frac{71}{20} - \frac{5}{3} \\ = \frac{213}{60} - \frac{100}{60} \\ = \frac{113}{60} \\ = 1 \frac{53}{60} [/tex]
  • 9/5 + 7/4 - 5/3
    = 108/60 + 105/60 - 100/60
    = 113/60
    = 1 53/60
