colin is thinking of a group of numbers between 40,000 and 60,000 that rounds to

54,450 .Use an organised list to fing Collins numbers

it has to be more than 54, 445 and less than 54,454. Right?

Are you rounding to the nearest 50? Or the nearest 10? Or the nearest 5?

Opps, Ms Sue is right. My answer applies to the nearest 10.

To find the possible numbers Colin is thinking of, we can use an organized list starting from 40,000 and going up to 60,000, checking which numbers round to 54,450.

Let's go step by step:

1. Start with the lowest number in the given range, which is 40,000.
2. Check if this number rounds to 54,450. To do that, you need to know the rounding convention being used. For example, if the convention is rounding to the nearest hundred, you would need to check if 40,000 is closer to 54,400 or 54,500.
3. If the number does not round to 54,450, move on to the next number.
4. Repeat steps 2-3 for each number in the range until you reach 60,000.

Here's an organized list of the numbers in the given range (40,000 to 60,000) that you can check:

40,100
40,200
40,300
...
54,400
54,500 <- possibly Colin's number
54,600
...
59,900
60,000

By going through this list and applying the rounding convention, you can find the number that matches Colin's given rounding value of 54,450.
