1) |-15,1| + |-25 \frac{5}{6}|
|-15,1| = 15,1
|-25 \frac{5}{6}| = 25 \frac{5}{6} = 25 + \frac{5}{6} = 25 + 0,833... = 25,833...
15,1 + 25,833... = 40,933...
2) |-5,3| - |-1 \frac{3}{5}|
|-5,3| = 5,3
|-1 \frac{3}{5}| = 1 \frac{3}{5} = 1 + \frac{3}{5} = 1 + 0,6 = 1,6
5,3 - 1,6 = 3,7
Ответ: 1) 40,933...; 2) 3,7.
