No, you do not need to express the answer in scientific notation unless the problem asks for it. Your question about rounding confuses me a little. You have 4 significant figures (sf) in 154.4 and 5 sf in 175.00; therefore, you are allowed 4 significant figures in the answer. I found 154.4/175.00 = 0.8822857. Rounded to 4 sf that will be 0.8823. I hope this helps.
