a)mai mici cu 3/10 decât 6/10;8/10;9/10;10/10
Facem scădere!
[tex] \bf{fractia \: cu \: \frac{3}{10} mai \: mica \: decât \: \frac{a}{b}} \\ \\ \bf \boxed{\frac{a}{b} - \frac{3}{10} }[/tex]
[tex]\bf \frac{6}{10} - \frac{3}{10} = \frac{6 - 3}{10} = \frac{3}{10} \\ \\\bf \frac{8}{10} - \frac{3}{10} = \frac{8 - 3}{10} = \frac{5}{10} {}^{(5} = \frac{1}{2} \\ \\ \bf \frac{9}{10} - \frac{3}{10} = \frac{9 - 3}{10} = \frac{6}{10} {}^{(2} = \frac{3}{5} [/tex]

b)mai mari cu 2/9 decât 5/9;7/9;3/9;6/9
Facem adunare!
