Question

is 1.05 can be a round off of 1.6632??

Answer 1

we observe the general trend, it appears that for rounding off to a place, all the places before that place must have a zero. Thus, when we want to round off a number to nearest thousands, we look at the values with zero at ones, tens and hundreds place, nearest to this number. Further, the value nearest to this number is its roundoff.

As an example let us round off 3467 correct to nearest thousands. 3467 lies between 3000 and 4000. As can be seen, 3000 is nearest to 3467. Therefore the rounded value of 3467 is 3000 correct to thousands. It is important to realize that numbers 1 to 499 are nearer to 0 than 1000 whereas numbers 500 to 999 are nearer to 100
