They are: 0.35 and 0.39 respectively

Rounded to the nearest tenth, there can be only one decimal. And that is 7.8
It would be 32.07. Rounded to the nearest tenth would be 32.1.

If you are rounding to the nearest tenth (the first decimal position), it is 6050.3, since the 8 in the hundredths position would cause the 2 to round up to 3. If you are rounding to the nearest tens (not a decimal, but the second position to the left of the decimal point), it is 6050. If you are rounding to the nearest 10 decimal places, it is 6050.2870000000.
Rounded to the nearest tenth, there can be only one decimal. And that is 7.8
35% as a decimal is 0.35 and rounded to the nearest tenth it is 0.4
11.0
It is 0.0 : the zero after the decimal point is an indication that the number is rounded to the nearest tenth.
With all decimal numbers, the position immediately to the right of the decimal point is the tenths place. Next to the right is the hundredths place, then the thousandths and so on. So 0.067 to the nearest hundredths place is 0.07 (the 6 is increased because what follows is greater than 5). To the nearest tenths it is 0.1: the 0 is increased to 1 since what follows is greater than 5).
It would be 32.07. Rounded to the nearest tenth would be 32.1.
