a) [tex]\frac{15}{15}[/tex] + [tex]\frac{50}{10}[/tex] = [tex]\frac{65}{150}[/tex]
b) [tex]\frac{32}{16}[/tex] + [tex]\frac{26}{13}[/tex] = [tex]\frac{58}{208}[/tex]
c) [tex]\frac{9}{8}[/tex] + [tex]\frac{18}{18}[/tex] = [tex]\frac{27}{144}[/tex]
d) [tex]\frac{14}{14}[/tex] + [tex]\frac{3}{3}[/tex] = 1
