我想問一下
28.711/30 s = 0.957
依個係唔係正確?
定係take 2 significant figures , 即係 0.96 ?
仲有 , 如果 68.874 / 50 係唔係都只take 2 significant figures ?
咁 68.874 / 113 係唔係就 take 3 significant figures ?
significant figure 好急!!!

✔ 最佳答案
You need to take into account the uncertainities of the raw figures (i.e. the values in the numerator and denominator) and the percentage error of the calculated result.Should the raw figures be exact values, rounding up of the result becomes arbitrary.
