Answer:
[tex]\frac{1}{6}[/tex] fraction of the total money.
Step-by-step explanation:
Trey, Marco, and Tina won a cash prize at a talent show.
They decided to share the money evenly between them.
So, if the prize money is $x, then each of them gets [tex]\frac{x}{3}[/tex] amounts of money.
Now, Trey gives half of his money to his little sister.
So, his sister gets [tex]\frac{x}{3} \times \frac{1}{2} = \frac{x}{6}[/tex] amounts of money.
Therefore, Trey keeps for himself [tex]\frac{x}{3} - \frac{x}{6} = \frac{x}{6}[/tex] amounts of money.
So, it is [tex]\frac{1}{6}[/tex] fraction of the total money. (Answer)
