Answer:
11/20
Step-by-step explanation:
4/5 and 1/4 clearly dont have the same denominator so you have to make them the same, to do so you would take 4/5 and multiply the 5 by 4 getting twenty, whatever you do to the top you do to the bottom so now you multipy 4 by 4 getting 16.
now you have made 4/5 into 16/20
next, your gonna change 1/4 so to make the 4 to a 20 you multiply it by 5 next you multiply the numerator (1) by 5 getting 5/20
now, you subtract 16/20 by 5/20
[tex]\frac{16}{20} -\frac{5}{20} =\frac{11}{20}[/tex] so, your answer is 11/20 (you cant simplify ne ways so yuh)
[tex]\\ \sf\Rrightarrow \dfrac{4}{5}-\dfrac{1}{4}[/tex]
- LCM of 5,4 is 20
[tex]\\ \sf\Rrightarrow \dfrac{4(4)-5(1)}{20}[/tex]
[tex]\\ \sf\Rrightarrow \dfrac{16-5}{20}[/tex]
[tex]\\ \sf\Rrightarrow \dfrac{11}{20}[/tex]
[tex]\\ \sf\Rrightarrow \smile[/tex]
