Calculati(+3\4)+(-5\24)+(+7\8)+(-1\16)
(-7\36)+(-5\18)+(-1\24)+(+11\48)
(-5\48)+(+7\18)+(_1\36)+(-11\12)

Answer 1

18/24 - 5/24 + 21/24 - 1/16 = (18 - 5 + 21)/24 - 1/16 = 34/24 - 1/16 = 17/12 - 1/16 =  (17× 4 - 3)/48 = 65/48

-7/36 - 5/18 -1/24 + 11/48 = -7/36 - 10/36 - 2/48 + 11/48 = -17/36 + 9/48 = -17/36 + 3/16 = (-17×4 + 3×9)/144 = ( -68 + 27)/144 = - 41/144

-5/48 + 14/36 - 1/36 - 44/48 = -49/48  + 13/36 = (-49×3 + 13×4)/144 = (-147 + 52)/144 = -95/144
