Question

x +1/12=2/3 atunci x=

Answer 1

x + 1 / 12 = 2 / 3
aducem la acelasi numitor care este 12
12x + 1 = 8
12 x = 8 - 1
12 x = 9
x = 9 / 12

Answer 2

$x + \frac{1}{12} = \frac{2}{3} \\ \\ x = \frac{2}{3} - \frac{1}{12} \\ \\ x = \frac{16}{24} - \frac{2}{24} \\ \\ x = \frac{14}{24}$

$x = \frac{7}{12}$

$Am~amplificat~pe~ \frac{1}{12}~cu~2,iar~pe~ \frac{2}{3}~cu~8~ca~sa~putem~aduce~fractiile~ \\ la ~acelasi~numitor,numitorul~comun~fiind~24.$ $la~sfarsit~, \frac{14}{24} ~il~amplificam~cu~2$
