\(\dfrac{11}{27}\cdot\dfrac{5}{3}+\dfrac{5}{3}\cdot\dfrac{16}{27}\)
\(=\dfrac{5}{3}\left(\dfrac{11}{27}+\dfrac{16}{27}\right)\)
\(=\dfrac{5}{3}\)
\(\dfrac{11}{27}x\dfrac{5}{3}+\dfrac{5}{3}x\dfrac{16}{27}\)
\(=\dfrac{5}{3}x\left(\dfrac{11}{27}+\dfrac{16}{27}\right)\)
\(=\dfrac{5}{3}x\dfrac{27}{27}=\dfrac{5}{3}x1=\dfrac{5}{3}\)
11/27 × 5/3 + 5/3 × 16/27
= 5/3 × (11/27 + 16/27)
= 5/3 × 1
= 5/3
