Приведем дроби к новому знаменателю:
- 3/8 = (3*3)/(8*3) = 9/24;
- 6/11 = (6*7)/(11*7) = 42/77;
- 2/3 = (2*7)/(3*7) = 14/21;
- 5/7 = (5*5)/(7*5) = 25/35;
- 8/10 = (8*4)/(10*4) = 32/40;
- 4/5 = (4*9)/(5*9) = 36/45.
Ответ: 3/8 = 9/24; 6/11 = 42/77; 2/3 = 14/21; 5/7 = 25/35; 8/10 = 32/40; 4/5 = 36/45.
