1) $$|9.6| - |-4.7| = 9.6 - 4.7 = 4.9$$.
2) $$|-5.8| \cdot |-1.3| = 5.8 \cdot 1.3 = 7.54$$.
3) $$|-15.2| - |-9.4| = 15.2 - 9.4 = 5.8$$.
4) $$\frac{7}{15} + |-\frac{5}{18}| = \frac{7}{15} + \frac{5}{18} = \frac{7 \cdot 6}{15 \cdot 6} + \frac{5 \cdot 5}{18 \cdot 5} = \frac{42}{90} + \frac{25}{90} = \frac{67}{90}$$.
5) $$|-63| \div |-0.9| = 63 \div 0.9 = 630 \div 9 = 70$$.
Ответ: 1) 4.9; 2) 7.54; 3) 5.8; 4) ; 5) 70.
