Приведи дроби к наименьшему общему знаменателю.Если возможно,вначале сократи их: а) 1/2, 125/150,28/63 б) 4/21,16/56 и 17/35
а) 1/2 125/150=5/6 28/63=4/9 НОЗ-18 9/18, 15/18, 8/18
б) 4/21, 16/56=2/7, 17/35 НОЗ- 105 20/105, 30/105, 51/105
а) 1/2 = 9/18
125/150 = 5/6 = 15/18
28/63 = 4/9 = 8/18
б) 4/21 = 20/105
16/56 = 2/7 = 30/105
17/35 = 51/105
