\(=5-\dfrac{3\times10}{5\times9}=5-\dfrac{30}{45}=5-\dfrac{2}{3}=\dfrac{15-2}{3}=\dfrac{13}{3}\)
\(=5-\dfrac{3}{5}\times\dfrac{10}{9}=5-\dfrac{5}{3}=\dfrac{15-5}{3}=\dfrac{10}{3}\)
\(=5-\dfrac{2}{3}=\dfrac{15}{3}-\dfrac{2}{3}=\dfrac{15-2}{3}=\dfrac{13}{3}\)
\(5-\dfrac{3}{5}\times\dfrac{10}{9}=5-\dfrac{30}{45}=5-\dfrac{2}{3}=\dfrac{75}{15}-\dfrac{10}{15}=\dfrac{65}{15}=\dfrac{13}{3}\)
