Un intreg 0,5 supra 7= x supra 2
Va rog frumos și explicat

Answer 1

  
[tex]\displaystyle\\ 1\frac{0,\!5}{7} = \frac{x}{2}~~~~~\text{Introducem intregii in fractie.}\\\\ \frac{1\cdot 7 +0,\!5}{7} = \frac{x}{2}\\\\ \frac{7,\!5}{7} = \frac{x}{2}\\\\ \frac{x}{2}=\frac{7,\!5}{7}~~~~~\Big| \cdot 2 \\\\ x = 2\cdot \frac{7,\!5}{7} = \frac{2\cdot 7,\!5}{7}= \boxed{\bf \frac{15}{7}} =\boxed{\bf 2\frac{1}{7}} [/tex]
