\(\frac{31}{53}.\frac{17}{28}+\frac{31}{28}.\frac{11}{53}\)
\(=\frac{31}{53}.\frac{17}{28}+\frac{11}{28}.\frac{31}{53}\)
\(=\frac{31}{53}.\left(\frac{17}{28}+\frac{11}{28}\right)\)
\(=\frac{31}{53}.1\)
\(=\frac{31}{53}\)
\(\frac{31}{53}\times\frac{17}{28}+\frac{31}{28}\times\frac{11}{53}\)
\(=\frac{31}{53}\times\frac{17}{28}+\frac{31}{53}\times\frac{11}{28}\)
\(=\frac{31}{53}\times\left(\frac{17}{28}+\frac{11}{28}\right)\)
\(=\frac{31}{53}\times1\)
\(=\frac{31}{53}\)
\(\frac{31}{53}.\frac{17}{28}+\frac{31}{28}.\frac{11}{53}=\frac{31}{53}.\frac{17}{28}+\frac{31}{53}.\frac{11}{28}\)
\(=\frac{31}{53}.\left(\frac{17}{28}+\frac{11}{28}\right)=\frac{31}{53}.1=\frac{31}{53}.\)
