- \((5\frac56+8\frac29):25.3=\frac{125}{18}:\frac{253}{10}=\frac{625}{2277}\), ал \(1.5:\frac{27}{28}=\frac{14}{9}\). Сондықтан нәтиже \(\frac{625}{2277}-\frac{28}{9}+\frac{14}{9}=\frac{625}{2277}-\frac{14}{9}=-\frac{2921}{2277}\). Жауабы: \(-\frac{2921}{2277}\).
- \(117.5\cdot\frac4{47}=10\), \(10\frac2{25}-8\frac7{15}=\frac{116}{75}\), оны \(\frac{11}{45}\)-ке бөлсек \(\frac{348}{55}\).
\(10-11\frac23+\frac{348}{55}=\frac{155}{33}\). Жауабы: \(\frac{155}{33}=4\frac{23}{33}\). - \(73.6-72\frac59=\frac{52}{45}\), ал \(6\frac4{15}=\frac{94}{15}\), бірінші бөлік \(\frac{26}{141}\). Екінші бөлік: \(\frac7{13}(20\frac23-19\frac37)=\frac7{13}\cdot\frac{46}{21}=\frac{46}{39}\).
Қосындысы \(\frac{26}{141}+\frac{46}{39}=\frac{160}{141}\). Жауабы: \(\frac{160}{141}=1\frac{19}{141}\). - \(81\frac2{15}-79.3=\frac{28}{15}\), \(24.04-22.68=1.36=\frac{34}{25}\), \(1\frac23+1\frac19=\frac{25}{9}\).
\(\frac{28}{15}\cdot\frac{34}{25}\cdot\frac{25}{9}=\frac{952}{135}=7\frac7{135}\). Жауабы: \(7\frac7{135}\). - \(52.25-49\frac17=\frac{43}{7}\), \(40.01-36.81=3.2=\frac{16}{5}\), \(6\frac16-2\frac1{42}=\frac{172}{30}=\frac{86}{15}\).
\(\frac{43}{7}\cdot\frac{16}{5}:\frac{86}{15}=\frac{24}{7}\). Жауабы: \(\frac{24}{7}=3\frac37\). - \(28.24-29.1=-0.86=-\frac{43}{50}\), \(11.75+30\frac56=\frac{511}{12}\), \(40.4-6\frac13=\frac{511}{15}\).
\(-\frac{43}{50}\cdot\frac{511}{12}:\frac{511}{15}=-\frac{43}{40}\). Жауабы: \(-1\frac3{40}\).
