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

We are given ratio 456:8.
The given ratio can be written in fraction form as
In order to find the rate, we need to divide 456 by 8, because it would give the unit value.
When we divide 456 by 8, we first take multiple of 8 closer to the number 45.
8*6=48 but it's greater than 45, so we would take 8*5 =40.
Subtracting 40 from 45, we get 5.
Getting 6 down, we get 56. Take multiple of 8 upto 56.
8*7= 56.
56 -56=0.
So, on dividing 456 by 8 we got 57.
Therefore, rate is 57 per unit.
Answer:
2,000 miles
Step-by-step explanation:
We are given:
This can be rewritten as:
This is representative of a unit rate, as we have a in the denominator. To calculate the number of miles in
inches, simply multiply the unit rate by
:
This can rewritten as:
Therefore, there are 2,000 miles in 4 inches.

We can check our solution by simplifying the fraction by dividing both
and
by
to see if we achieve the unit rate:
Since this is in fact the unit rate, our solution is correct!
