The greatest magnitude possible is just short of 50%. That occurs when a number just smaller than 15 is rounded down to 10.

You will get the greatest product if you choose the greatest possible numbers in both cases, i.e., 9 x 99.
It depends what criteria you are using.Normally anything over plus point five of a number is rounded up, anything below is rounded down
9 times the number

There is no "greatest possible". All we know about it is that it must be less than 7.775,but it's not possible to name the "greatest" number that's less than 7.775 .Whatever number you offer, no matter how close it is to 7.775, I can always name anothernumber that's greater than yours, and closer to 7.775 but still not over it.Example:Your number: 7.774999999999999999My number . : 7.774999999999999999000000000000001
The greatest possible 'length' comes from the number with the greatest number of prime factors. The greatest number of factors is created by using the smallest prime number, 2, as a factor as many times as possible. Since 2^9=512 and 2^10=1024, the greatest possible 'length' of a positive integer less than 1000 is 9.

The answer depends on the degree of rounding: to the nearest 2400000, it is a fraction less than 3600000.
600
The answer will depend on the degree to which the number is rounded. Without any indication of that, it is not possible to answer the question sensibly. The general answer is that it could be any positive number smaller than 150000.
