3) Сравнить дроби: 1) 3 18/24; 2) 25/75; 3) 42/126; 4) 4 23/77; 5) 8 35/84; 6) 48/72; 7) 6 34/50; 8) 10 15/63.

1. \(3\dfrac{18}{24}=3\dfrac{3}{4}\).
2. \(\dfrac{25}{75}=\dfrac{1}{3}\).
3. \(\dfrac{42}{126}=\dfrac{1}{3}\).
4. \(4\dfrac{23}{77}=4\dfrac{1}{?}\) — дробь \(\dfrac{23}{77}\) не сокращается.
5. \(8\dfrac{35}{84}=8\dfrac{5}{12}\).
6. \(\dfrac{48}{72}=\dfrac{2}{3}\).
7. \(6\dfrac{34}{50}=6\dfrac{17}{25}\).
8. \(10\dfrac{15}{63}=10\dfrac{5}{21}\).
