7. Найди значение выражения: 1) |-15,1| + |-25 \frac{5}{6}|; 2) |-5,3| - |-1 \frac{3}{5}|

1) \( |-15,1| + |-25 \frac{5}{6}| \) \(|-15,1| = 15,1\) \(|-25 \frac{5}{6}| = 25 \frac{5}{6} = 25,833...\) \(15,1 + 25 \frac{5}{6} = 15,1 + 25,833... = 40,933... = 40 \frac{14}{15}\) 2) \( |-5,3| - |-1 \frac{3}{5}| \) \(|-5,3| = 5,3\) \(|-1 \frac{3}{5}| = 1 \frac{3}{5} = 1,6\) \(5,3 - 1,6 = 3,7\) Ответ: 1) \(40 \frac{14}{15}\) 2) 3,7
