### Topic

Representing Kim Kardashian’s irrational wedding into a rational number

### Student Exploration

In 2011, reality television star Kim Kardashian and basketball player Kris Humphries got married. After their very short-lived marriage, Kim decided to donate twice the value of all of her wedding gifts to charity. All of the wedding gifts’ worth was estimated at $100,000, so she donated$200,000 to the Dream Foundation. We can write a rational fraction to represent the amount she donated to her net worth. Looking at the link given below, her net worth is approximately \$35 million. Let’s write this as a rational number and simplify.

200,00035,000,000=2350=1175\begin{align*}\frac{200,000}{35,000,000}=\frac{2}{350}=\frac{1}{175}\end{align*}

This represents a proper fraction, and represents the fraction of the money that was given in relation to how much she is worth. She donated one one-hundred-seventy-fifth of her net worth to charity.

### Extension Investigation

Do you think this is fair? Do you feel that she should have donated more or less money to charity, based on your knowledge of this celebrity?
