Привет, ребята! Давайте сократим дроби, разложив числитель и знаменатель на простые множители.
1. **24/15**:
- 24 = 2 * 2 * 2 * 3
- 15 = 3 * 5
- 24/15 = (2 * 2 * 2 * 3) / (3 * 5) = (2 * 2 * 2) / 5 = 8/5
2. **36/60**:
- 36 = 2 * 2 * 3 * 3
- 60 = 2 * 2 * 3 * 5
- 36/60 = (2 * 2 * 3 * 3) / (2 * 2 * 3 * 5) = 3/5
3. **56/72**:
- 56 = 2 * 2 * 2 * 7
- 72 = 2 * 2 * 2 * 3 * 3
- 56/72 = (2 * 2 * 2 * 7) / (2 * 2 * 2 * 3 * 3) = 7/9
4. **42/66**:
- 42 = 2 * 3 * 7
- 66 = 2 * 3 * 11
- 42/66 = (2 * 3 * 7) / (2 * 3 * 11) = 7/11
5. **54/81**:
- 54 = 2 * 3 * 3 * 3
- 81 = 3 * 3 * 3 * 3
- 54/81 = (2 * 3 * 3 * 3) / (3 * 3 * 3 * 3) = 2/3
6. **84/90**:
- 84 = 2 * 2 * 3 * 7
- 90 = 2 * 3 * 3 * 5
- 84/90 = (2 * 2 * 3 * 7) / (2 * 3 * 3 * 5) = (2 * 7) / (3 * 5) = 14/15
**Ответы:**
- 24/15 = 8/5
- 36/60 = 3/5
- 56/72 = 7/9
- 42/66 = 7/11
- 54/81 = 2/3
- 84/90 = 14/15
