You need to find the common denominator, which is 20.
4/5=16/20
1/4=5/20
16/20-5/20=11/20
The answer is 11/20.

(4)/(5) - (1)/(4)

Find the least common denominator :

4 * 5 = 20

Adjust fractions based on the LCD


(4*4)/(20) - (5)/(20)



(4*4-5)/(20)


(16-5)/(20)


= (11)/(20)

hope this helps!
