Answer 1

Ответ:

$-\frac{1}{3}$

Пошаговое объяснение:

$6\frac{13}{24}-(14 \frac{7}{24} -10\frac{31}{48})-(2 \frac{3}{4}- \frac{7}{12} )-1\frac{1}{16} = \frac{157}{24}-( \frac{343}{24}- \frac{511}{48})-(\frac{11}{4}-\frac{7}{12})- \frac{17}{16}=\\\frac{157}{24}-( \frac{686-511}{48})-(\frac{33-7}{12})- \frac{17}{16} =\frac{157}{24}-\frac{175}{48}-\frac{13}{6}- \frac{17}{16} =\frac{314-175-10-51}{48} =-\frac{1}{3}$

Answer 2

Ответ:

-1/3

Пошаговое объяснение:

1) 14 7/24 - 10 31/48 = 14 14/48 - 10 31/48 =

13 62/48 - 10 31/48 = 3 31/48

2) 2 3/4 - 7/12 = 2 9/12 - 7/12 = 2 2/12 = 2 1/6

3) 6 13/24 - 3 31/48 = 6 26/48 - 3 31/48 =

5 74/48 - 3 31/48 = 2 43/48

4) 2 43/48 - 2 1/6 = 2 43/48 - 2 8/48 = 35/48

5) 35/48 - 1 1/16 = 35/48 - 1 3/48 = 35/48 - 51/48 = -16/48 = -1/3
