Answer 2

Number of Yellow books Anil bought $= 5 \frac{2}{3} = \frac{17}{3}$

Number of Red books Anil bought $=7 \frac{5}{6} = \frac{47}{6}$

Number of Blue books Anil bought$=5 \frac{7}{9} = \frac{52}{9}$

Total Books he bought $= \frac{17}{3}+ \frac{47}{6} + \frac{52}{9}$

$LCM = 18 \\ \sf \implies\frac{102 + 141 + 104}{18} \\ \sf \implies\frac{347}{18} \\ \sf \implies19 \frac{5}{18}$
