When converting 49.81 dag to hg and rounding to the nearest tenth, the result is:

(a) 0.5 hg
(b) 5.0 hg
(c) 4.9 hg
(d) 0.05 hg

Answer 1

To convert 49.81 dag to hg, divide by 10 to get 4.981 hg, which is rounded to the nearest tenth as 5.0 hg. The correct answer is (b) 5.0 hg.

Step-by-step explanation:

The question is asking to convert the mass from dekagrams (dag) to hectograms (hg) and then round the result to the nearest tenth. First, to do the conversion, we need to know the relationship between these two units of mass. There are 10 dag in 1 hg. To convert 49.81 dag to hg, we divide by 10:

49.81 dag ÷ 10 = 4.981 hg

Next, we round this to the nearest tenth, which is 5.0 hg. Therefore, the correct answer is (b) 5.0 hg.
