No Robert is not correct because his better long jump was 1.33 foot farther than May's better long jump.

Step-by-step explanation:

Mays jumps

(i) $4\frac{2}{3}$

=> $\frac{12+2}{3}$

=> $\frac{14}{3}$

=>4.667

(ii) $4\frac{3}{4}$

=> $\frac{16+3}{4}$

=> $\frac{19}{4}$

=>4.75

May's better long jump is $4\frac{3}{4}$

Robert jumps :

(i) $6\frac{1}{12}$

=> $\frac{72+1}{12}$

=> $\frac{73}{12}$

=>6.08

(ii) $5\frac{2}{3}$

=> $\frac{15+2}{3}$

=> $\frac{17}{3}$

=> 5.66

Robert's better long jump is $6\frac{1}{12}$

Now the difference between Robert's better long jump and May's better long jump is

=> $6\frac{1}{12} - 4\frac{3}{4}$

=> $\frac{72+1}{12} - \frac{16+3}{4}$

=> $\frac{73}{12} - \frac{19}{4}$

=>6.08 - 4.75

=> 1.33
