my answer does not match the answer key which is 2.0 x 10^3.[/B]
When i did the problem , i ended up get 3 SF answer. The numerator simplies to 504.996 where the sigfigs should be 3 because 0 is the least number of decimals. The denominator is simplified to 0.25007333 where the sigfigs is 4 because 4 is the least number of sig figs. So, when i divide, i get 2019.391672. Since, 3 is the least number of Sigfigs, the answer should be 2.02 x 10^3.
BUT, the answer key is saying otherwise! What am i doing wrong? Am i using the rules right?
