\(\left[\dfrac{2}{3}+\dfrac{11}{15}\right].2\)
\(=\left[\dfrac{10}{15}+\dfrac{11}{15}\right].2\)
\(=\dfrac{7}{5}.2\)
\(=\dfrac{14}{5}\)
=(10/15+11/15)*2=21/15*2=7/5*2=14/5
\(\dfrac{2}{3}\) + \(\dfrac{11}{15}\) x 2
= \(\dfrac{2}{3}\) + \(\dfrac{22}{15}\)
=\(\dfrac{10}{15}\) + \(\dfrac{22}{15}\)
= \(\dfrac{14}{5}\)
( \(\dfrac{2}{3}\) + \(\dfrac{11}{15}\) ) x 2 = \(\dfrac{7}{5}\) x 2 = \(\dfrac{14}{5}\)
