Answer 1

Пошаговое объяснение:

Пошаговое объяснение:

(1/12+1/6) : (3/8-1/4) = (1/12+2/12) : (3/8-2/8) = 3/12 : 1/8 =1/4 * 8/1 = 2/1=2

(1 - 4/9) : (1/3 -1/4) = 5/9 : (4/12 - 3/12) = 5/9 ÷ 1/12=5/9×12/1=(5×4)/(3×1)=20/3=6 2/3

(1/3 -5/16) : (1/6-1/8) = (16/48 - 15/48) : (4/24 - 3/24) = 1/48 : 1/24 = 1/48×24/1=24/48=1/2

(5/7 - 2/3) : (4/9 - 5/12) = (15/21 - 14/21) : (16/36 - 15/36) = 1/21 : 1/36 =

= 1/21 * 36/1 = 36/21 = 12/7 = 1 5/7

Пошаговое объяснение:

$\frac{1}{2} - \frac{1}{3} =\frac{3}{6}-\frac{2}{6}=\frac{1}{6} \\\frac{5}{6} - \frac{2}{3}=\frac{5}{6}-\frac{4}{6}= \frac{1}{6}\\\frac{3}{8} + \frac{1}{4} =\frac{3}{8} +\frac{2}{8}=\frac{5}{8} \\\frac{5}{9}-\frac{2}{5}=\frac{25}{45} -\frac{18}{45} =\frac{7}{45}\\ \frac{9}{16}-\frac{1}{2} =\frac{9}{16} -\frac{8}{16}=\frac{1}{16} \\6-2.5=3.5$
