Question

x-1phần 4=5 phần 6×4 phần 9

Answer 1

\(x-\dfrac{1}{4}=\dfrac{5}{6}\times\dfrac{4}{9}\)

<=>\(x-\dfrac{1}{4}=\dfrac{10}{27}\)

<=>\(x=\dfrac{10}{27}+\dfrac{1}{4}=\dfrac{67}{108}\)

Answer 2

\(x-\dfrac{1}{4}=\dfrac{5}{6}\times\dfrac{4}{9}\\ \Rightarrow x-\dfrac{1}{4}=\dfrac{10}{27}\\ \Rightarrow x=\dfrac{10}{27}+\dfrac{1}{4}\\ \Rightarrow x=\dfrac{67}{108}\)
