2)1-(⁷/¹²-²/¹⁵)
3)⁶/⁷×⁷/¹²:⁵/¹⁶
помогите пж​

Answer 1

Ответ:

Пошаговое объяснение:

$1) \frac{5}{6} +\frac{2}{9}-\frac{1}{6}\\\\ \frac{5-1}{6} + \frac{2}{9} \\\\\frac{4}{6} + \frac{2}{9} \\\\\frac{2}{3} + \frac{2}{9} \\\\\frac{6+2}{9} \\\\\frac{8}{9}$

$2) 1-(\frac{7}{12} - \frac{2}{15} )\\\\1-\frac{9}{20} \\\\\frac{11}{20}$

$3) \frac{6}{7}*\frac{7}{12} / \frac{5}{16}\\\\\frac{1}{2} / \frac{5}{16}\\\\\frac{1}{2} *\frac{16}{5} \\\\\frac{8}{5}= 1\frac{3}{5}=1,6$

Answer 2

Пошаговое объяснение:

1)

5/6 + 2/9 - 1/6 = (5/6 - 1/6) + 2/9 =

4/6 + 2/9 = 12/18 + 4/18 = 16/18 = 8/9

2)

1 - (7/12 - 2/15) = 1 - (35/60 - 8/60) =

1 - 27/60 = 60/60 - 27/60 = 33/60 = 11/20

3)

6/7 * 7/12 : 5/16 = 1/1 * 1/2 : 5/16 = 1/2 * 16/5 = 1/1 * 8/5 = 8/5 = 1 3/5
