\(\dfrac{8}{15}-x:\dfrac{3}{4}=\dfrac{11}{18}\)
\(x:\dfrac{3}{4}=\dfrac{8}{5}-\dfrac{11}{18}\)
\(x:\dfrac{3}{4}=-\dfrac{7}{90}\)
\(x=-\dfrac{7}{90}\cdot\dfrac{3}{4}\)
\(x=-\dfrac{7}{120}\)
\(\Rightarrow x:\dfrac{3}{4}=\dfrac{8}{15}-\dfrac{11}{18}\\ \Rightarrow x:\dfrac{3}{4}=-\dfrac{7}{90}\\ \Rightarrow x=-\dfrac{7}{90}\times\dfrac{3}{4}\\ \Rightarrow x=-\dfrac{7}{120}\)
\(\dfrac{8}{15}-x:\dfrac{3}{4}=\dfrac{11}{18}\)
\(\Rightarrow x:\dfrac{3}{4}=\dfrac{8}{15}-\dfrac{11}{18}\)
\(\Rightarrow x:\dfrac{3}{4}=\dfrac{144}{270}-\dfrac{165}{270}\)
\(\Rightarrow x:\dfrac{3}{4}=\dfrac{-7}{90}\)
\(\Rightarrow x=\dfrac{-7}{90}\times\dfrac{3}{4}\)
\(\Rightarrow x=\dfrac{-7}{120}\)
\(\dfrac{8}{15}-x:\dfrac{3}{4}=\dfrac{11}{18}\)
\(x:\dfrac{3}{4}=\dfrac{8}{15}-\dfrac{11}{18}\)
\(x:\dfrac{3}{4}=\dfrac{48}{90}-\dfrac{55}{90}\)
\(x:\dfrac{3}{4}=\dfrac{-7}{90}\)
\(x=\dfrac{-7}{90}.\dfrac{3}{4}\)
\(x=\dfrac{-21}{360}\)
\(x=\dfrac{-7}{120}\)
Vậy \(x=\dfrac{-7}{120}\)
\(8/15 - x:3/4 =11/18 \)
\(8/15 -x = 11/18 .3/4\)
\(8/15 -x = 11/24 \)
\(x = 8/15 -11/24\)
\(x = 61/24\)
