21.848 to 2 decimal points is 21.85 as you round up the final decimal
To 4 DP, 62.1935 To 3 DP, 62.194 To 2 DP, 62.19 To 1 DP, 62.2
The height, is 6.3 metres (to 2 dp).The height, is 6.3 metres (to 2 dp).The height, is 6.3 metres (to 2 dp).The height, is 6.3 metres (to 2 dp).
To 1 dp it is 1.0; to 2 dp it is 1.00; to 3 dp it is 1.000
It is: 5.58
4.46 is a fixed number: it has no upper nor lower bound. To 2 dp it is 4.46
Count the numbers of digits after the decimal points (DP) in the two numbers.Add these numbers together.Calculate the product, including any trailing 0s.Place the DP so that the number of digits after the DP is the same as the sum of the digits after the DP (step 2).Thus, for 15.38 * 0.0045The first number has 2 digits after the DP, the second has 4, so sum of digits after DP is 2+4 = 6.1538*0045 = 69210.The answer must have 6 digits after the DP so you need to insert a 0 after the DP to make it .069210 which can then be simplified to .06921
It depends how many decimal places or significant figures you are rounding to.Here's the general method for if you're rounding to 2 dp (decimal places);Look at the number in the 3rd dp spot. Is it 5 or above?If no, write the number with only 2 dp ignoring the 3rd dp number completely. If yes, you'll need to increase the number in the 2nd decimal place spot by 1, unless ...The 2nd dp number is a 9 (as it is in the above question). In that case you need to increase the 1st dp number by 1 and make the 9 a zero. Unless ...The 1st dp number is a 9 ..... etc. etc.So for our example;Rounding to;2 dp = 8.201 dp = 8.20 dp = 8
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.
