Answer: 3 11/20
Step-by-step explanation:
You would first simplify 3 3/4 which is 15/4 then you would subtract it with 1/5
Next, you would have to find the GCD ( greatest common factor) for 15/4 and 1/5 which is 20 so multiply 15 by 5 and 4 by 5 which is 75/20, then multiply the top and bottom with 4 for 1/5 which is 4/20 . You then would subtract the simplified forms 75/20 with 4/20 Which is 71/20 which u can simplify to
3 11/20.
