Răspuns:
a)
[tex] \frac{17 - 15}{3} = \frac{2}{3} [/tex]
b) simplificăm fractia prin 9
[tex] \frac{243 - 126}{945} = \frac{117}{945} = \frac{13}{105} [/tex]
c)
[tex] \frac{118 - 105}{23} = \frac{13}{23} [/tex]
d)
[tex] \frac{89 - 14}{75} = \frac{75}{75} = 1[/tex]
e)
[tex] \frac{30 - 15}{98} = \frac{15}{98} [/tex]
f)
[tex] \frac{14 - 3}{150} = \frac{11}{150} [/tex]
g) simplificăm prima fractie prin 2, si a doua prin 3
[tex] \frac{1}{10} - \frac{1}{15} = \frac{3 - 2}{30} = \frac{1}{30} [/tex]
