Ally collects stickers as a hobby. She gives her sisters of her stickers.
sertanlavr [38]

Answer:

\frac{16}{25}

Step-by-step explanation:

Ally gives her sister = 1/5 stickers

Ally gives her cousin = 1/5 of the remainder stickers

Assume Number of sticker Ali has = 1

Remainder after giving stickers to her sister = 1 - 1/5 = 4/5

Number of stickers she gave her sister = \frac{1}{5}\times\frac{4}{5}

         =\frac{4}{25}

Sticker she has = 1-\frac{1}{5}-\frac{4}{25}

=\frac{25-5-4}{25}

=\frac{16}{25}

Sticker left with Ally is equal to \frac{16}{25}.
