$13/20$

To add or subtract fractions, they have to have the same denominators. We use the small possible common denominator.

IN this case both 5 and 20 can divide into 20, so this is the LCD.

Covert to equivalent fractions and then add the numerators.

$2/5 + 5/20 = (2xx4)/(5xx4) + 5/20$

$= (8+5)/20 = 13/20$
