Mays jumps : 4 2/3 and 4 3/4
Robert jumps : 6 1/12 and 5 2/3
May:
- 4 2/3 = 12+2/3 = 14/3 = 4.667 ft
- 4 3/4 = 16+3/4 = 19/4 = 4.75 ft
Her best jump = 4.75
Robert:
- 6 1/2 = 72+1/12 = 73/12 = 6.08 ft
- 5 2/3 = 15+2/3 = 17/3 = 5.66 ft
His best jump = 6.08 ft
6.08- 4.75 = 1.33 ft --> about 1 (if you round it!)
