Answer:

"The sum of two rational numbers is rational."

By definition, a rational number can be expressed as a fraction with integer values in the numerator and denominator (denominator not zero). So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.

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 $\frac{16}{25}$ .
