Ответ:
- а) \(4\frac{13}{24}+\frac18-3\frac1{24}=1+\left(\frac{13}{24}+\frac3{24}-\frac1{24}\right)=1+\frac{15}{24}=\frac58+1=1\frac58\).
- б) \(3\frac89+1\frac34+\frac19=4+\left(\frac89+\frac19\right)+\frac34=4+1+\frac34=5\frac34\).
- в) \(5\frac12-2\frac7{12}-2\frac3{10}=1+\frac{30}{60}-\frac{35}{60}-\frac{18}{60}=1-\frac{23}{60}=\frac{37}{60}\).
- г) \(4\frac23+2\frac34-1\frac5{12}=5+\frac8{12}+\frac9{12}-\frac5{12}=5+1=6\).
Ответ: а) \(1\frac58\); б) \(5\frac34\); в) \(\frac{37}{60}\); г) \(6\).
