№1. Сократить числовую дробь: 1) 12/48; 2) −55/242; 3) −128/300; 4) −66/220; 5) −500/750; 6) 501/1002.

1. \(\dfrac{12}{48}=\dfrac{1}{4}\).
2. \(\dfrac{-55}{242}=\dfrac{-5}{22}\).
3. \(\dfrac{-128}{300}=\dfrac{-32}{75}\).
4. \(\dfrac{-66}{220}=\dfrac{-3}{10}\).
5. \(\dfrac{-500}{750}=\dfrac{-2}{3}\).
6. \(\dfrac{501}{1002}=\dfrac{1}{2}\).

Ответ: 1) \(\frac14\); 2) \(-\frac5{22}\); 3) \(-\frac{32}{75}\); 4) \(-\frac3{10}\); 5) \(-\frac23\); 6) \(\frac12\).
