It is already rounded to 2 dp.
Do absolutely nothing. 0.67 IS already rounded to 2 dp.
15.54 is rounded to 2 decimal places and it makes little sense to express a number from 2 dp to 3 dp but, since you have asked, the answer is 15.540
If the number is truly 1, and you are wanting it with 2 decimal places, then your answer is: 1.00
0.1 If you round something to 1 decimal place, you can only have one number after the decimal point, eg 0.109 is 0.1 rounded to 1 decimal place 0.109 is 0.11 rounded to 2 decimal places
.9 is already rounded to 1 decimal place. To 2 dp it is 0.90
1.555... or 1.56 rounded (to 2 dp).
It is already rounded to 2 dp.

15.54 is rounded to 2 decimal places and it makes little sense to express a number from 2 dp to 3 dp but, since you have asked, the answer is 15.540
To 4 DP, 62.1935 To 3 DP, 62.194 To 2 DP, 62.19 To 1 DP, 62.2
82.383 to 3 dp 82.38 to 2 dp 82.4 to 1 dp
log(43116) = 4.6346 which, rounded to 2 dp, is 4.63
To 1 dp it is 1.0; to 2 dp it is 1.00; to 3 dp it is 1.000
42.06 units rounded to 2 dp
You would not round 1.66 to 2.0. 1.66 is a number given to two decimal places (dp). To the nearest 1 dp it would be rounded to 1.7, not to 2.0 And, to 0 decimal places, it would be rounded to 2, not 2.0. Although in most respects, 2 and 2.0 are equivalent, in terms of rounding they are not. 2.0 implies a greater degree of precision.
There are infinitely many possible answers.For example, 1, 2, 3, 4 and 37or -4, -3, -2, -1 and 57.Or you can use numbers to 1 decimal place (dp), 2 dp, 3 dp and so on.
