Calculati:1 Supra 2+ 1 supra 4,1 supra 3 +5 supra 6,1 supra 4 + 3 supra8,2 supra 5+3 supra 10,3 supra4+5 supra6, 5 supra 7 +4 supra 9

Answer 1

Răspuns:

Explicație pas cu pas:

$\frac{ {}^{2)} 1}{2} + \frac{1}{4} = \frac{2}{4} + \frac{1}{4}= \frac{2 + 1}{4} = \frac{3}{4}$

___________

$\frac{ {}^{2)} 1}{3} + \frac{5}{6} = \frac{2}{6} + \frac{5}{6}= \frac{2 + 5}{6} = \frac{7}{6}$

___________

$\frac{ {}^{2)} 1}{4} + \frac{3}{8} = \frac{2}{8} + \frac{3}{8}= \frac{2 + 3}{8} = \frac{5}{8}$

___________

$\frac{ {}^{2)} 2}{5} + \frac{3}{10} = \frac{4}{10} + \frac{3}{10} =\frac{4 + 3}{10} = \frac{7}{10}$

___________

$\frac{ {}^{3)} 3}{4} + \frac{ {}^{2)} 5}{6}= \frac{9}{12} + \frac{10}{12} = \frac{9 + 10}{12} = \frac{19}{12}$

____________

$\frac{ {}^{9)} 5}{7} + \frac{ {}^{7)} 4}{9} =\frac{45}{63} + \frac{28}{63} =\frac{45 + 28}{63} = \frac{73}{63}$
