А) 1 1/6 б) - 5/36 в) - 7/18 г) 6/15
Пошаговое объяснение:
А) - 3/10 + (-13/15) = - (9/30 + 26/30) = - 35/30 = 1 5/30 = 1 1/6
Б) 7/12 + (-13/18) = 21/36 + (-26/36) = - (26/36 - 21/36) = - 5/36
В) - 1/9 - 5/18 = - 2/18 + (-5/18) = - (2/18 + 5/18) = - 7/18
Г) - 1/3 - (-11/15) = - 5/15 + 11/15 = (11/15 - 5/15) = 6/15
А) 1 1/6 б) - 5/36 в) - 7/18 г) 6/15
Пошаговое объяснение:
А) - 3/10 + (-13/15) = - (9/30 + 26/30) = - 35/30 = 1 5/30 = 1 1/6
Б) 7/12 + (-13/18) = 21/36 + (-26/36) = - (26/36 - 21/36) = - 5/36
В) - 1/9 - 5/18 = - 2/18 + (-5/18) = - (2/18 + 5/18) = - 7/18
Г) - 1/3 - (-11/15) = - 5/15 + 11/15 = (11/15 - 5/15) = 6/15
