A
Step-by-step explanation:
You convert each fraction to have the same decimal to find the LCD of both denominators
4, 8, 12, 16, 20 and 5, 10, 15, 20 = both of them have 20 in common
You multiply the numerator and denominator by 5 for 2 3/4 and for 5 4/5 you multiply both the numerator and denominator by 4
2 15/20 and 5 16/20
Subtract them and their is your answer

1/5,764,801
