a, \(\frac{7}{3}=>2\frac{1}{3}\); \(\frac{53}{17}=>3\frac{2}{17};\frac{60}{21}=>2\frac{18}{21};\frac{76}{15}=>5\frac{1}{15};\frac{45}{14}=>3\frac{3}{14}\)
b, \(\frac{22}{3}=>7\frac{1}{3};\frac{57}{8}=>7\frac{1}{8};\frac{123}{11}=>11\frac{2}{11};\frac{139}{13}=>10\frac{9}{13};\frac{9}{2}=>4\frac{1}{2}\)
k cho mình nhé.
