Answer 1

thời xưa chắc không có ghi vở

Answer 2

\(3\frac{1}{2}=\frac{3.2+1}{2}=\frac{7}{2}\)

\(13\frac{2}{3}=\frac{13.3+2}{3}=\frac{41}{3}\)

\(5\frac{7}{8}=\frac{5.8+7}{8}=\frac{47}{8}\)

\(17\frac{1}{4}=\frac{17.4+1}{4}=\frac{69}{4}\)

\(4\frac{2}{9}=\frac{4.9+2}{9}=\frac{38}{9}\)

\(21\frac{5}{9}=\frac{21.9+5}{9}=\frac{194}{9}\)

\(10\frac{5}{8}=\frac{10.8+5}{8}=\frac{85}{8}\)

\(14\frac{1}{5}=\frac{14.5+1}{5}=\frac{71}{5}\)

Answer 3

\(3\frac{1}{2}=\frac{7}{2}\)

\(13\frac{2}{3}=\frac{41}{3}\)

\(5\frac{7}{8}=\frac{47}{8}\)

\(17\frac{1}{4}=\frac{69}{4}\)

\(4\frac{2}{9}=\frac{38}{9}\)

\(21\frac{5}{9}=\frac{194}{9}\)

\(10\frac{5}{8}=\frac{85}{8}\)

\(14\frac{1}{5}=\frac{71}{5}\)
