So we have 21.8 divided by 16.9. 1st and foremost, just plug this into your calculator and we get something to the effect of 1.28994. But now we need to follow the rules of significant figures. Now, the rule for significant figures for either multiplication or division is we look at both the terms and then we find the lowest significant figure count. So let's see here, the significant figures for the term 21.8 is three. But we can also see that this is the number of significant figures in 16.9 meaning that we need to round this number up to three significant figures. So once we do that, we are going to get 1.29 that is three significant figures and this corresponds to answer choice. C Thank you all so much for watching. I hope this video helped.
