Question

Simplificatii fractia, apoi efectuati scaderea:
[tex] \frac{7}{70} - \frac{10}{100} =?

Efectuati:
[tex]
(\frac{5}{6} + \frac{7}{6} )=?
\frac{4}{3} -( \frac{9}{11} + \frac{2}{11}0=?[/tex]

Answer 1

1.$\frac{7}{70} = \frac{1}{10}$ (a fost simplificat cu 7)
$\frac{10}{100}$ $=\frac{1}{10}$ (simplificat cu 10)
$\frac{1}{10} - \frac{1}{10} = 0.$
2. $\frac{5}{6} + \frac{7}{6} = \frac{12}{6} =2.$
[tex] \frac{4}{3} - ( \frac{9}{11} + \frac{2}{11} ) = \frac{4}{3} - \frac{11}{11} = \frac{4}{3} - 1; 1 = \frac{3}{3} =\ \textgreater \ \frac{4}{3} - \frac{3}{3} = \frac{1}{3} .[/tex]
