Question

(12/35-7/20)*(-1-1/6)

Answer 1

aducem la acelasi numitor in paranteze 140 la prima este numitorul comun, iar la a2a 6

(48-49)/140 * (-6-1)/6=

= (-1/140) * ( -7/6)=

= 1/20 * 1/6=  1/120

Answer 2

$( \frac{12}{35} - \frac{7}{20}) * (-1 - \frac{1}{6}) = ( \frac{48}{140} - \frac{49}{140} ) * ( \frac{-6 - 1}{6} ) =$

= $\frac{-1}{140} * \frac{-7}{6} = \frac{1}{20 * 6} = \frac{1}{120}$
