Question

{3+ {2/3 - (1/3 + 2/3) + 1/6 ] + 4

Answer 1

$3 + [\frac{2}{3} - ( \frac{1}{3} + \frac{2}{3}) + \frac{1}{6}] + 4$
$3 + [\frac{2}{3} - \frac{3}{3} + \frac{1}{6}] + 4$
$3 + [ -\frac{1}{3} + \frac{1}{6} ] + 4$
$3 + [ \frac{-2+1}{6} ]+4$
$3 - \frac{1}{6} + 4$
m.m.c de 1.6.1
$\frac{18-1+24}{6}$
$\frac{42 - 1}{6}$
$7 - 1 = 6$
