One Way:
We can change the mixed number to a decimal for comparing.

$1\frac{1}{4}$ m = $\frac{5}{4}$ 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.

$1\frac{1}{4}$ = $\frac{5}{4}$ (Luke)
1.4 = $\frac{7}{5}$ (Darren)
We need a common denominator to compare
$\frac{5*5}{4*5}$ (Luke)
$\frac{7*4}{5*4}$ (Darren)
$\frac{25}{20}$ (Luke)
$\frac{28}{20}$ (Darren)

$\frac{28}{20} > \frac{25}{20}$
  Darren >    Luke

By:
$\frac{28}{20}$ - $\frac{25}{20}$ = $\frac{3}{20}$
Which is also by 0.15 m
Darren jumps higher and by 0.15 m
