5) 750/1125, 1000/3175, 1250/2250, 675/975, 1008/1224, 1188/1485

1. Сократим каждую дробь:

1. 750/1125 = (250*3)/(250*4.5) = 2/3
2. 1000/3175 = (25*40)/(25*127) = 40/127
3. 1250/2250 = (250*5)/(250*9) = 5/9
4. 675/975 = (75*9)/(75*13) = 9/13
5. 1008/1224 = (72*14)/(72*17) = 14/17
6. 1188/1485 = (132*9)/(132*11.25) = 9/11.25 = 36/45 = 4/5

2. Сокращенные дроби:

2/3, 40/127, 5/9, 9/13, 14/17, 4/5
