Ответ:
- \(-3.7+(-5.93)=-9.63\).
- \(7.421-8.51=-1.089\).
- \(-4.76-(-5.92)=-4.76+5.92=1.16\).
- \(-\frac47+3\frac5{14}=-\frac8{14}+\frac{47}{14}=\frac{39}{14}=2\frac5{14}\).
- \(\frac38-\frac5{12}=\frac9{24}-\frac{10}{24}=-\frac1{24}\).
- \(\frac34:\left(-\frac53\right)=\frac34\cdot\left(-\frac35\right)=-\frac9{20}\).
- \(-\frac38:\frac54=-\frac38\cdot\frac45=-\frac3{10}\).
- \((-0.5)\cdot(-0.2)=0.1\).
- \(3.2\cdot(-0.3)=-0.96\).
- \(-\frac4{15}\cdot\frac5{24}=-\frac{20}{360}=-\frac1{18}\).
