1 5/13 • 2 3/5= [tex]\frac{18}{13} * \frac{13}{5} =\frac{234}{65} =3\frac{3}{5}[/tex]
6 3/4 : 1 4/5= [tex]\frac{27}{4} : \frac{9}{4} = \frac{27}{4}*\frac{4}{9} =\frac{108}{36} =3[/tex]
3 2/3 - 6 4/5= [tex]\frac{11}{4} - \frac{34}{5} =-4\frac{1}{20}[/tex]
7 2/9 - 3 4/5=[tex]3\frac{19}{45}[/tex]
5 1/3 - 2 6/7=[tex]2\frac{10}{21}[/tex]
7 6/11 - 4 7/33=[tex]3\frac{1}{3}[/tex]
