Ответ:
\(\frac4{10}+\frac{17}{25}-\frac6{15}=\frac25+\frac{17}{25}-\frac25=\frac{17}{25}\).
\(\frac{20}{30}+\frac7{12}-\frac9{16}=\frac23+\frac7{12}-\frac9{16}=\frac{11}{16}\).
\(\frac{17}{25}=0{,}68<0{,}6875=\frac{11}{16}\).
Ответ: \(\frac4{10}+\frac{17}{25}-\frac6{15}<\frac{20}{30}+\frac7{12}-\frac9{16}\).
