One Way:
We can change the mixed number to a decimal for comparing.
m = 
m = 1.25 m
1.4 m > 1.25 m
Darren > Luke
Darren's jump was higher by (1.4-1.25) 0.15 m
Or another way change the decimal to a fraction and the mixed to an improper fraction too.
= (Luke)
1.4 =
(Darren)
We need a common denominator to compare
(Luke)
(Darren)
(Luke)
(Darren)
Darren > Luke
By:
- = 
Which is also by 0.15 m
Darren jumps higher and by 0.15 m
