Question

Kristin received a $CD$ player for her birthday. She bought $3CDs$ and received $5$ other as gifts. What fraction of her total $CDs$ did she buy and what fraction did she receive as gifts ?

Answer 1

Total numbers of $C{D}^{\prime }s$ she had $=375=8$

$\Rightarrow$ fraction of total $C{D}^{\prime }s$ she bought $=\frac{C{D}^{\prime }sshebought}{Totalno.ofC{D}^{\prime }s}$

$=\frac{3}{8}$

$\Rightarrow$ fraction of total $C{D}^{\prime }s$ she received as gifts $=1-\frac{3}{8}$

$=\frac{5}{8}$
