a) [tex]\frac{32}{24}x + \frac{15}{24}x = \frac{47}{24}x = 1\frac{23}{24}x[/tex]
b) [tex]1\frac{2}{10}x + \frac{5}{8}x = \frac{12}{10}x + \frac{5}{8}x = \frac{96}{80}x + \frac{50}{80}x = \frac{146}{80}x = 1\frac{66}{80}x = 1\frac{3}{4}x[/tex]
c) [tex]\frac{3}{12}x + \frac{10}{12}x - \frac{6}{12}x = \frac{7}{12}x[/tex]
d)[tex]\frac{3}{7}x - \frac{2}{10}x + \frac{1}{1}x = \frac{30}{70}x - \frac{14}{70}x + \frac{70}{70}x = \frac{86}{70}x = 1\frac{16}{70}x = 1\frac{8}{35}x[/tex]
