[tex] \frac{3.3}{4} - \frac{2.2}{3} + 6 - \frac{3.5}{6} = \frac{33}{40} - \frac{22}{30} + 6 - \frac{35}{60} = \frac{33}{40} - \frac{11}{15} + 6 - \frac{35}{60} = \frac{99}{120} - \frac{88}{120} + \frac{720}{120} - \frac{35}{60} = \frac{11}{120} + \frac{720}{120} - \frac{35}{60} = \frac{731}{120} - \frac{35}{60} = \frac{731}{120} - \frac{70}{120} = \frac{661}{120} [/tex]
