Question

Chuyển phân số thành hỗn số : 15/9, 33/12, 221/20, 75/13 ai bik cách làm thì giúp tớ với tớ sẽ like cho.

Answer 1

\(\dfrac{15}{9}\) = 1\(\dfrac{6}{9}\); \(\dfrac{33}{12}\) = 2\(\dfrac{9}{12}\);    \(\dfrac{221}{20}\) = 11\(\dfrac{1}{20}\); \(\dfrac{75}{13}\) = 5\(\dfrac{10}{13}\)

Answer 2

\(\dfrac{15}{9}=\dfrac{15:3}{9:3}=\dfrac{5}{3}=1\dfrac{2}{3}\\ \dfrac{33}{12}=\dfrac{33:3}{12:3}=\dfrac{11}{4}=2\dfrac{3}{4}\\ \dfrac{221}{20}=\dfrac{20\times11+1}{20}=11\dfrac{1}{20}\\ \dfrac{75}{13}=\dfrac{13\times5+10}{13}=5\dfrac{10}{13}\)
