Answer:
6³/₁₀ 
Explanation:
Number of bits = Total amount/Size of each bit 
 = (4⅕)/(⅔) 
 
Convert the mixed number to an improper fraction 
No. = (²¹/₅)/(⅔) 
 
Invert the denominator and change division to multiplication 
No. = ²¹/₅ × ³/₂ 
 
Multiply numerators and denominators. 
No. = ⁶³/₁₀ 
 
Convert the improper fraction to a mixed number. 
No. = 6³/₁₀ 
It takes 6³/₁₀ ⅔s to make up 4⅕.
