- 42: $$|42| = 42$$
- 5,6: $$|5,6| = 5,6$$
- -3,1: $$|-3,1| = 3,1$$
- $$\frac{11}{15}$$: $$\left|\frac{11}{15}\right| = \frac{11}{15}$$
- $$\frac{-4}{9}$$: $$\left|-\frac{4}{9}\right| = \frac{4}{9}$$

Ответ: |42| = 42; |5,6| = 5,6; |-3,1| = 3,1; |$$\frac{11}{15}$$| = $$\frac{11}{15}$$; |$$\frac{-4}{9}$$| = $$\frac{4}{9}$$; |-7$$\frac{111}{400}$$| = 7$$\frac{111}{400}$$; |-37| = 37; |0| = 0
