If your target digit is a 9 and rounding makes it increase, the digit immediately to the left of it will increase by one. If that digit is a nine, the same thing applies. Otherwise, the digits to the left of the target are left as they were.
121.39 rounded off to the nearest hundredth is 121.39 itself, as there are no digits after the hundredth place.
0.45
Since the number contains two digits after the decimal point, it is already rounded to the nearest hundredth.
To 2 decimal places, 42.67 is 42.67 (There are already only 2 digits after the decimal point.)
The answer depends on the extent to which the number is being rounded, that is, which place is "given".

Three. All non-zero digits are significant, all zeroes between other digits, and all digits to the right of the decimal. The reason for this is that if this is rounded off, it apparently is rounded off to the nearest tenth, otherwise the tenth place would not be shown. if it were rounded off to the unit, it would read 39, not 39.0 ■
147.5
186 doen't have any decimal digits, so it's already "rounded to 1 decimal place".
0.45
I don't give beep bout thus
The thousandths place is the third digit after the decimal point. 86.255 only has 3 digits after the decimal point so it is already (possibly) rounded to the nearest thousandth.
This could be anything from 0.35 to 0.44 if just talking about figures in the hundredths place
The mystery number is 155. When rounded to the nearest hundred, it rounds to 200. The sum of its digits is 1+5+5=11 which is greater than 10, so we must adjust the digit in the hundreds place. When rounded to the nearest ten, 155 rounds to 160, which has digits summing up to 1+6+0=7.
