3 minus 5supra 5 ma poate ajuta cineva cineva ?

Răspuns :

3-5:5 = 3-1= 2 
Si gata!
[tex]3- \frac{5}{5} = \frac{3}{1} - \frac{5}{5} \\\\ ~~~~~~~~= \frac{3*5}{1*5} - \frac{5}{5} \\\\ ~~~~~~~~= \frac{15}{5} - \frac{5}{5} \\\\ ~~~~~~~~= \frac{10}{5} \\\\ ~~~~~~~~=2\\\\\\ sau...\\ \frac{3-5}{5} = \frac{-2}{5} (in~caz~ca~totul~este~supra~5) [/tex]
