Решение:

Находим модули чисел:

1. a) \( |7| = 7 \)
2. \( |-7| = 7 \)
3. \( |-15| = 15 \)
4. \( |+41| = 41 \)
5. \( |0| = 0 \)
6. б) \( |42,6| = 42,6 \)
7. \( |+5,7| = 5,7 \)
8. \( |-1000,81| = 1000,81 \)
9. в) \( \left|-\frac{1}{70}\right| = \frac{1}{70} \)
10. \( \left|-99\frac{1}{3}\right| = 99\frac{1}{3} \)
11. \( |+22,3| = 22,3 \)
12. \( \left|\frac{7}{5}\right| = \frac{7}{5} \)
13. \( \left|\frac{5}{6}\right| = \frac{5}{6} \)
14. \( |1| = 1 \)
