The answer would be 72.94 ml/times
In this problem, the infant is fed for every 4 hours. Then, the frequency of feeding for a day would be: (24hours/day) / 4 (hours/times)= 6 times/ day.
The volume of feeding for a day that the infant need would be: 2722 g/(<span>454 g/73ml)= 473.68ml
The number of milk for every fed would be: (</span>473.68ml/day)/ (6 times/day)= 72.94 ml/times
