a) \(10\frac{11}{24}-x=6\frac{7}{16}\)
\(x=10\frac{11}{24}-6\frac{7}{16}\)
\(x=10\frac{22}{48}-6\frac{21}{48}\)
\(x=4\frac{1}{48}\)
б) \(x-4\frac{3}{7}=8\frac{9}{14}\)
\(x=8\frac{9}{14}+4\frac{3}{7}\)
\(x=8\frac{9}{14}+4\frac{6}{14}\)
\(x=12\frac{15}{14}\)
\(x=13\frac{1}{14}\)
Ответ: a) \(4\frac{1}{48}\); б) \(13\frac{1}{14}\)
