Kristin received a CD player for her birthday. She bought 3 CDs and received 5 others as gifts. What fraction of her total CDs did she buy and what fraction did she receive as gifts?
Given:
CDs bought by Kristin = 3
CDs received as gifts = 5
To find: We have to find what fraction of kristin total CDs did she buy and what fraction did she receive as gifts
Solution:
Total number of CDs = CDs bought by Kristin + CDs received as gifts
= 3 + 5
= 8
Now,
Fraction of CD's bought by kristin = $ \begin{array}{l} \frac{CD's\ brought\ by\ kristin}{Total\ number\ of\ CD's}\ \end{array}$
= $\frac{3}{8}$
Fraction of CD's received as gifts = $ \begin{array}{l} \frac{CD's\ received\ as\ gifts}{Total\ number\ of\ CD's}\ \end{array}$
= $\frac{5}{8}$
