Solution
The correct option is A Dennis < Ella < Justin
To finish the race:
Ella takes 1,456 seconds.
Justin takes 1,564 seconds.
Dennis takes 1,425 seconds.
To arrange them in ascending order, we need to compare the numbers first.
So, let us write the numbers in the place value chart.
Since the digit at the thousands place is same, so we first compare the digits at the hundreds place.
By comparing the digits at the hundreds place, we can see that Justin takes the most time.
Now, we compare the digit at the tens place for Ella and Dennis.
We can see that Dennis has taken the least time.
So, we can say that Ella has taken more time than Dennis but less than Justin.
Hence, after arranging the time taken in the ascending order, we get:
