Пошаговое объяснение:
1) НОК (12; 8) = 24
7/12 и 5/8 => (7*2)/(12*2) и (5*3)/(8*3) =>
14/24 и 15/24
2) НОК (9; 15) = 45
2/9 и 4/15 => (2*5)/(9*5) и (4*3)/(15*3) =>
10/45 и 12/45
3) НОК (25; 15) = 75
7/25 и 2/15 => (7*3)/(25*3) и (2*5)/(15*5) =>
21/75 и 10/75
4) НОК (16; 24) = 48
3/16 и 5/24 => (3*3)/(16*3) и (5*2)/(24*2) =>
9/48 и 10/48
