Question

Can u please answer this question

Answer 1

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


`1(1)/(4)` m =
`(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(1)/(4)` =
`(5)/(4)` (Luke)
1.4 =
`(7)/(5)` (Darren)
We need a common denominator to compare

`(5*5)/(4*5)` (Luke)

`(7*4)/(5*4)` (Darren)

`(25)/(20)` (Luke)

`(28)/(20)` (Darren)


`(28)/(20)  >   (25)/(20)`
Darren > Luke

By:

`(28)/(20)` -
`(25)/(20)` =
`(3)/(20)`
Which is also by 0.15 m
Darren jumps higher and by 0.15 m
