If it is "correct to 1/10th of a kilogram", that means that the meximum error is 1/2 that amount, in other words, 1/20th of a kilogram. I suggest you convert everything to grams first - 1 kilogram = 1000 grams.
Neither is correct. The nearest correct statement that can be constructed from anything close to the given materials is: "Eight and eight are sixteen."

The answer depends on the extent of rounding used for 1000. It is always a problem with integers ending in zero(s). You do not (cannot) know whether the number is 1000 to the nearest thousand (range = 500 to 1500), or to the nearest 100 (950 to 1050), nearest 10 (995 to 1005) or unit (999.5 to 1000.5)If the number is 1000 to the nearest thousand, the answer could be anything between 1.785 and 5.355. So the answer should be given as "3.57 with a range of 1.785 to 5.355".If the number is 1000 to the nearest hundred, the answer should be given as "3.57 with a range of 3.3915 to 3.7485".If the number is 1000 to the nearest ten, the answer should be given as "3.6 to two sf".If the number is 1000 to the nearest ten or unit, the answer is 3.57
The lower bound is 0.5 less and the upper bound is 0.5 more.

Can't round to the nearest 100th because the number is not given to the 1000th place. You could answer 235.50, although that is not technically correct. Nearest tenth, 235.5 Nearest whole number, 236. Nearest 10, 240 Nearest 100, 200
Round 45,621 to the nearest place given. To the nearest ten
27.8 IS given to the nearest tenth.
In three dimensions, the solid defined as being bound by the set of points at a given distance form a point is a sphere. In two dimensions, the figure defined as being bound by the set of points at a given distance from a point is a circle. In one dimension, a line segment is bound by the two points at a given distance from a point.
I assume you are talking in terms of rounding, in which case subtract/add half the value to which the number is rounded to get the lower and upper bounds, and then the lower bound is inclusive and the upper bound is exclusive:To the nearest whole number: 999.5 ≤ x < 1000.5To the nearest 2: 999 ≤ x < 1001To the nearest 4: 998 ≤ x < 1002To the nearest 5: 997.5 ≤ x < 1002.5To the nearest 8: 996 ≤ x < 1004To the nearest 10: 995 ≤ x < 1005To the nearest 20: 990 ≤ x < 1010To the nearest 25: 987.5 ≤ x < 1012.5To the nearest 40: 980 ≤ x < 1020To the nearest 50: 975 ≤ x < 1025To the nearest 100: 950 ≤ x < 1050To the nearest 125: 937.5 ≤ x < 1067.5To the nearest 200: 900 ≤ x < 1100To the nearest 250: 875 ≤ x < 1125To the nearest 500: 750 ≤ x < 1250To the nearest 1000: 500 ≤ x < 1500
