Mathematics

Brittany is sharing number of $\frac{1}{15}$ s with her sister = 6

Step-by-step explanation:

Let the shell collection of Brittany = x

She is giving $\frac{2}{5}$ of her shell collection to her sister.

Therefore, shells received by her sister = $\frac{2x}{5}$

$\frac{1}{15}$ th of her shell collection = $\frac{x}{15}$

Number of $\frac{1}{15}$ s her sister received = $\frac{\text{Total shells received by Brittany's sister}}{\frac{1}{15}th \text{part of Brittany's shells}}$

= $\frac{\frac{2x}{5}}{\frac{x}{15} }$

= $\frac{2x}{5}\times \frac{15}{x}$

= 6

Therefore, number of $\frac{1}{15}$ received by her sister = 6
