The fraction computed shows that the total inches the infant grew over the three months is 3 3/4 inches.
First month = 2/4 inches
Second month = 1 inch
Third month = 7/4 inches.
The total inches the infant grew over the three months will be;
= 2/4 + 1 + 7/4
= 3 1/4 inches.
The difference in the infants from the second month to the third month will be:
= 7/4 - 1
= 3/4 inches.
