Ответ:
- а) \(13\frac{1}{7}-9\frac{1}{2}=\frac{92}{7}-\frac{19}{2}=\frac{184-133}{14}=\frac{51}{14}=3\frac{9}{14}\).
- б) \(5\frac{1}{2}:1\frac{1}{11}=\frac{11}{2}:\frac{12}{11}=\frac{11}{2}\cdot\frac{11}{12}=\frac{121}{24}=5\frac{1}{24}\).
- в) \(3,5-4,8-21,7+13,5=-9,5\).
- г) \(0,3036:(-0,23)=-1,32\).
- д) \(5,5\cdot1\frac{1}{11}:(13\frac{1}{7}-9\frac{1}{2})=\frac{11}{2}\cdot\frac{12}{11}:\frac{51}{14}=6\cdot\frac{14}{51}=\frac{28}{17}=1\frac{11}{17}\).
Ответ: а) 3 9/14; б) 5 1/24; в) −9,5; г) −1,32; д) 1 11/17.
