Question

(-11/12+5/18)*(-9/46)+(-5/42-(-11/28)):(- 1 13/28)РЕШИТЕ!!!!!!

Answer 1

-11/12+5/18 = -33/36 + 10/36 = -23/36 = - 23/36
-23/36 * (-9/46) = 23*9/36*46 = 1/8
-5/42- (-11/28) = -5/42+11/28 = -10/84 +33/84 = 23/84
1/8+23/84= 21/168 +46/168 = 67/168
67/168 / (-1 13/28) = 67 /168  / 41/28  = 67 /246
