Answer:

\frac{9}{16}

Step-by-step explanation:

Let total number of students=x

Students went to the book fair:

Students went to book fair=\frac{15}{20}\times total\ number\ of\ students=\frac{15}{20}x

Students who bought book:

Students\ who\ bought\ book=\frac{12}{16}\times Number\ of\ students\ went\ to\ book\ fair=\frac{12}{16}\times \frac{15}{20}x=\frac{9}{16}x

Hence \frac{9}{16} of total students bought at least one book.

vivado [14]

2\dfrac{1}{5}+1\dfrac{1}{10}=2+\dfrac{1}{5}+1+\dfrac{1}{10}=(2+1)+\left(\dfrac{1}{5}+\dfrac{1}{10}\right)\\\\=3+\left(\dfrac{1\cdot2}{5\cdot2}+\dfrac{1}{10}\right)=3+\left(\dfrac{2}{10}+\dfrac{1}{10}\right)=3+\dfrac{2+1}{10}=\boxed{3\dfrac{3}{10}}
