không rút được hay gì á

5 / 9 nhé

HTN

rút gọn phân số sau

\(\frac{85}{153}=\frac{85:17}{153:17}=\frac{5}{9}\)

học vui~!!!

85/153=5/9

\(\frac{85}{153}\)\(=\frac{85:17}{153:17}\)\(=\frac{5}{9}\)

a) \(\dfrac{11\cdot8-11\cdot3}{17-6}\)

\(=\dfrac{11\cdot\left(8-3\right)}{11}=5\)

b) \(\dfrac{24-12\cdot13}{12+4\cdot9}\)

\(=\dfrac{12\cdot\left(2-13\right)}{12\left(1+3\right)}=\dfrac{-11}{4}\)
