Помогите пожалуйста Разделите дроби: 48⁄15 : 22⁄3 23⁄5 : (5⁄9 + 5,3) (3,5 − 11/3) : 2/13
48/15: 22/3 = 48/15 * 3/22 = 24/5 * 1/11 = 24/55 23/5:( 5/9+5,3) = 23/5: (5/9+53/10) = 23/5: (50/90+477/90) = 23/5 * 90/527 = 414/2635 (3,5-11/3): 2/13 = (35/10-11/3): 2/13 = (105/30-110/30): 2/13 = 5/30: 2/13 = 1/6 * 13/2 = 13/12 = 1 1/12
