\(6*8*5/9*24*10=1/9\) Tương tự vs các câu còn lại nhé =)
a: \(=\dfrac{6}{24}\cdot\dfrac{8}{9}\cdot\dfrac{5}{10}=\dfrac{1}{8}\cdot\dfrac{8}{9}=\dfrac{1}{9}\)
b: \(=\dfrac{12}{18}\cdot\dfrac{14}{21}\cdot13=\dfrac{2}{3}\cdot\dfrac{2}{3}\cdot13=\dfrac{52}{9}\)
c: \(=\dfrac{2323}{4646}\cdot\dfrac{123123}{234234}=\dfrac{1}{2}\cdot\dfrac{123}{234}=\dfrac{41}{156}\)
