1.564 - 0.38 = 1.184
The "correct" precision depends on the calibration of your measuring device. Since we don't know that, here are the possible choices:
To the nearest whole number: 1
To the nearest tenth: 1.2
To the nearest hundredth: 1.18
To the nearest thousandth: 1.184
146 rounded to hundredths would be 146, but could be written as 146.00 to indicate the precision.
0.20
If you are rounding to the nearest tens, it is correct that 63 is rounded to 60.
Correct!
The correct answer is 0.9
1.184
146 rounded to hundredths would be 146, but could be written as 146.00 to indicate the precision.
That depends with what precision you want to round it. When rounded to the nearest whole number, the answer is 267. If rounded to the nearest 10, it is 270. If rounded to the nearest hundred, 300. If rounded to the nearest thousand, the answer is zero.
0.20
If you are rounding to the nearest tens, it is correct that 63 is rounded to 60.
They should be. Certainly before presenting results.

The term accuracy describes how far your observation/measurement is from the correct result. Precision describes how repeatable your results are, regardless of their accuracy..
Precision is how to keep track of good a measuring device is. Accuracy is how close an answer is to being correct. Something can be precise but not accurate. Something can be accurate but not precise.
Correct!
