- \( -23.25-0.9=-(23.25+0.9)=-24.15 \).
- \( -45.08-28=-(45.08+28)=-73.08 \).
- \( -44.9-23.9=-(44.9+23.9)=-68.8 \).
- \( -0.5-10.1=-(0.5+10.1)=-10.6 \).
- \( -4.15-7.7=-(4.15+7.7)=-11.85 \).
- \( -39.2-5.6=-(39.2+5.6)=-44.8 \).
- \( -\frac{3}{65}-\left(-\frac{1}{130}\right)=-\frac{6}{130}+\frac{1}{130}=-\frac{5}{130}=-\frac{1}{26} \).
- \( -\frac{1}{54}-\frac{3}{162}=-\frac{1}{54}-\frac{1}{54}=-\frac{2}{54}=-\frac{1}{27} \).
- \( 7\frac{1}{24}-\left(-3\frac{7}{72}\right)=7\frac{3}{72}+3\frac{7}{72}=10\frac{10}{72}=10\frac{5}{36} \).
- \( -0.35-2\frac{1}{20}=-0.35-2.05=-2.4 \).
- \( 9.48-41\frac{7}{25}=9.48-41.28=-31.8 \).
- \( -19.27-1\frac{3}{40}=-19.27-1.075=-20.345 \).
