Ответ:
- \( -1\frac{1}{5}\cdot(-15)=\frac{-6}{5}\cdot(-15)=18 \).
- \( -1.95-8.68=-10.63 \).
- \( -7-(-4)+3=-7+4+3=0 \).
- \( -2.16:\left(5\frac{3}{20}\right)=-\frac{54}{25}:\frac{103}{20}=-\frac{216}{515} \).
- \( 1\frac{1}{8}-3\frac{5}{6}=\frac{9}{8}-\frac{23}{6}=\frac{27-92}{24}=-\frac{65}{24}=-2\frac{17}{24} \).
Ответ: 1) 18; 2) −10,63; 3) 0; 4) −216/515; 5) −2 17/24.
