Question from Linda: Sam and Mary each owned one-half stock in a printing company. Sam sold 2/5 of his stock to Mary. What fractional part of the printing business does Mary now own? |
Linda,
Let's say the company was worth $10 million.
Sam has half and so does Mary. So Sam's stock is $5 million and Mary's is $5 million.
Now Sam gives Mary 2/5 of his stock. What is 2/5 of $5 million? How much does Mary have now? What fraction of the whole $10 million is that?
Hope this helps,
Stephen La Rocque
