b) [tex]\frac{7}{9}[/tex]
c) [tex]\frac{30}{100}[/tex]
d) [tex]\frac{4}{8}[/tex]
e) [tex]\frac{1}{7}[/tex]
f) [tex]\frac{2}{4}[/tex]
g) [tex]\frac{4}{10}[/tex]
h) [tex]\frac{40}{100}[/tex]
Explicație pas cu pas:
a) [tex]\frac{15}{10} - \frac{12}{10} = \frac{15-12}{10} = \frac{3}{10}[/tex]
b) [tex]\frac{17}{9} - \frac{10}{9} = \frac{17-10}{9} = \frac{7}{9}[/tex]
c) [tex]\frac{80}{100} - \frac{50}{100} = \frac{30}{100}[/tex]
d) [tex]\frac{14}{8} - \frac{10}{8} = \frac{4}{8}[/tex]
e) [tex]\frac{5}{7} - \frac{4}{7} = \frac{1}{7}[/tex]
f) [tex]\frac{11}{4} - \frac{9}{4} = \frac{2}{4}[/tex]
g) [tex]\frac{10}{10} - \frac{2}{10} - \frac{4}{10} = \frac{10-2-4}{10} = \frac{8-4}{10} = \frac{4}{10}[/tex]
h) [tex]\frac{100}{100} - \frac{12}{100} - \frac{16}{100} - \frac{32}{100} = \frac{100-(12+16+32)}{100} = \frac{100-60}{100} = \frac{40}{100}[/tex]
