Решение:
- \( 1\frac{1}{2} - 2,3 = \frac{3}{2} - \frac{23}{10} = \frac{15}{10} - \frac{23}{10} = -\frac{8}{10} = -\frac{4}{5} \)
- \( (-\frac{4}{5})^2 = \frac{16}{25} \)
- \( \frac{16}{25} : (-\frac{1}{5}) = \frac{16}{25} \cdot (-5) = -\frac{16}{5} \)
- \( |-0,6| = 0,6 = \frac{6}{10} = \frac{3}{5} \)
- \( -\frac{16}{5} + \frac{3}{5} = -\frac{13}{5} \)
Ответ: -\(\frac{13}{5}\).
