ответ:
а) 3 2_15 + 1 2_5 / 1_3 - 2 1_5 = 5 2_15
б) ( 1 1_2 - 1_4 ) / 3 3_4 + 2_3 = 1
в) 4 5_6 - 5_8 - 2 1_4 * 1_6 = 3 5_6
г) (4 - 2 1_2 * 3_5) / 3 1_3 - 1_3 = 5_12
пошаговое объяснение:
а) 3 2_15 + 1 2_5 / 1_3 - 2 1_5
1) 1 2_5 / 1_3 = 4 1_5
2) 3 2_15 + 4 1_5 = 7 1_3
3) 7 3_5 - 2 1_5 = 5 2_5
б) ( 1 1_2 - 1_4 ) / 3 3_4 + 2_3 = 1
1) 1 1_2 - 1_4 = 1 2_4 - 1_4 = 1 1_4
2) 1 1_4 / 3 3_4 = 5_4 / 4_15 = 1_3
3) 1_3 + 2_3 = 1
в) 4 5_6 - 5_8 - 2 1_4 * 1_6
1) 2 1_4 * 1_6 = 9_4 * 1_6 = 3_8
2)4 5_6 - 5_8 = 4 20_24 - 15_24 = 4 5_24
3) 4 5_24 - 3_8 = 4 5_24 - 9_24 = 3 5_6
г) (4 - 2 1_2 * 3_5) / 3 1_3 - 1_3
1) 2 1_2 * 3_5 = 5_2 * 3_5 = 1 1_2
2) 4 - 1 1_2 = 3 2_2 - 1 1_2 = 2 1_2
3) 2 1 _2 : 3 1_3 = 3_4
4) 3_4 - 1_3 = 9_12 - 4_12 = 5_12
