2) 6 13/24-((14 7/24-10 31/48))-(2 3/4 - 1 7/12))- 1 1/16

Answer 1

$6\frac{13}{24} - ((14\frac{7}{24} - 10\frac{31}{48}) - (2\frac{3}{4}-1\frac{7}{12})) = 6\frac{26}{48} - ((14\frac{14}{48} - 10\frac{31}{48}) - (2\frac{36}{48}-1\frac{28}{48}))\\ \\= 6\frac{26}{48} - ((13\frac{62}{48} - 10\frac{31}{48}) - (2\frac{36}{48}-1\frac{28}{48}))= 6\frac{26}{48} - (3\frac{31}{48} - 1\frac{8}{48})\\ \\= 6\frac{26}{48} - 2\frac{23}{48} = 4\frac{3}{48} = 4\frac{1}{16}$
