[tex] \frac{17}{3} - \frac{15}{3} = \frac{17 - 15}{3} = \frac{2}{3} [/tex]
b)
[tex] \frac{243}{945} - \frac{126}{945} = \frac{24 3 - 126}{945} = \frac{117}{945} = \frac{39}{315} = \frac{13}{105} [/tex]
c)
[tex] \frac{118}{23} - \frac{105}{23} = \frac{118 - 105}{23} = \frac{13}{23} [/tex]
d)
[tex] \frac{89}{75} - \frac{14}{75} = \frac{89 - 14}{75} = \frac{75}{75} = \frac{1}{1} = 1[/tex]
