b) [tex]\frac{4}{5} >\frac{3}{5}[/tex]
c) [tex]\frac{8}{12} =\frac{6}{9}[/tex]
d) [tex]\frac{2}{3} >\frac{3}{5}[/tex]
2.
a) [tex]\frac{9}{4} +\frac{3}{4} +\frac{6}{4} =\frac{18}{4} =4\frac{2}{4}[/tex]
b) [tex]\frac{17}{7} +\frac{13}{7} =\frac{30}{7} =4\frac{2}{7}[/tex]
c) [tex]2-\frac{3}{8} =\frac{16}{8} -\frac{3}{8} =\frac{13}{8} =1\frac{5}{8}[/tex]
d) [tex]\frac{15}{6} -\frac{7}{6} =\frac{8}{6} =\frac{4}{3} =1\frac{1}{3}[/tex]
e) [tex]\frac{7}{3} -\frac{5}{3} =\frac{2}{3}[/tex]
f) [tex]3-\frac{8}{5} =\frac{15}{5} -\frac{8}{5} =\frac{7}{5} =1\frac{2}{5}[/tex]
