Question

3 pe langa minus 1 pe 6 plus 1 pe 2

Answer 1

3(-1/6 + 1/2)= 3(-1/6 + 3/6) = 3(1/3) = 3*1/3 = 1

Answer 2

$3( - \frac{1}{6} + \frac{1}{2}) = - \frac{1}{6} + \frac{1}{2} = \frac{ - 1}{6} + \frac{1 \times 3}{2 \times 3} = - \frac{1}{6} + \frac{3}{6} = \frac{ - 1 + 3}{6} = { \frac{2}{6} }^{(2} = \frac{1}{3} = 3 \times \frac{1}{3} = \frac{3 \times 1}{1 \times 3} = \frac{3}{3} = 1$
