Rounded to the nearest million, 754 is approximately equal to zero.

Any number greater than or equal to 745 but less than 755 can be rounded off to 750. This is because when rounding to the nearest 10, any number 5 or greater in the ones place will round up. Therefore, numbers like 746, 747, 748, 749, and 750 can all be rounded to 750.

When you round off 42 754 to the nearest thousands, you will have 40 000, and to ten thousands, you get 0.
It is 750.

39.5, 40.5 (to the nearest unit) 35 and 45 (to the nearest 10) 31 and 59 (to the nearest 20). Rather than round up 5s, I "round ties to even". This is the recommended default under the IEEE 754 technical standard which has been adopted internationally.
False.Many schools do teach you to round 5 up, always rounding up from 5 is inappropriate because it introduces an upward bias. The IEEE (Institute of Electronic and Electrical Engineers) standard 754 is to round 5 up or down so that the new last digit is even.

The tens' digit is 6. If what follows it is less than 5 then replace every digit following the tens' digit by 0s. If what follows is bigger than 5 then add 1 to the tens' digit and replace every digit following the tens' digit by 0s. If it is exactly 5 then make sure that the tens' digit is even and replace everything after it by 0s. Many naive teachers require that you round up (add 1 etc) when the next digit is 5. This introduces an upward bias and in statistically unsound. The solution is to round to odd or round to even. (See link). Mathematically, they are equivalent but, judging by the latter seems to be winning. It is the default mode in IEEE 754.
