To find how tall he was at the end of the school year, you add his height at the beginning of the year and during the school year. First you should just add the inches.
2 1/4 + 7/8
The common denominator is 8.
2 2/8 + 7/8
2 9/8
3 1/8
Put back in the 5 ft.
So, Jerry was 5ft and 3 1/8 inches at the end of the school year.
