Answer:

$\huge\boxed{\frac{5c}{4},\ or\ c+\frac{1}{4}c,\ or\ c+\frac{c}{4}}$

Step-by-step explanation:

The decimal 0.25 can simply be converted into a fraction by putting it over 100.

0.25 = $\frac{25}{100}$

Then, simply divide both the numerator and denominator by 25 to get

$\frac{25/25}{100/25}$ , or $\frac{1}{4}$

Hope it helps :)
