Eric is 17 inches tall than his brother.
Convert 6 feet 2 inches into just inches and convert 4 feet and 9 inches into inches.
Work:
6 x 12 = 72
72 + 2 = 74
Eric is 74 inches tall
4 x 12 = 48
48 + 9 = 57
Eric's brother is 57 inches tall
Subtract 74 - 57 = 17
Eric is 17 inches tall than his brother.
Hope this helps!
