\(1\dfrac{13}{15}\cdot0,75\cdot\left(\dfrac{8}{15}+0.25\right)\cdot\dfrac{24}{47}\)
= \(\dfrac{28}{15}\cdot\dfrac{3}{4}\cdot\left(\dfrac{8}{15}+\dfrac{1}{4}\right)\cdot\dfrac{24}{47}\)
= \(\dfrac{7}{5}\cdot\dfrac{47}{60}\cdot\dfrac{24}{47}\)
\(=\dfrac{329}{300}\cdot\dfrac{24}{47}\)
\(=\dfrac{14}{25}\)
= 28/15 x 3/4 ( 8/15 + 1/4 ) x 24/27
= 28/15 x 3/4 . 47/60 x 24/27
= 7/5 x 47/60 x 24/27
= 658/675
