It looks like the first measurement will only have 2 significant figures in its result, since "14." only has 2 significant figures. So, that one could be written as 2.9 * 10^2 The second measurement will also have 2 significant figures, since the multiple "12." so you could write it as 2.5 * 10^2 The third measurement would actually be closer to 2.617 than 2.7; in fact, since you can have up to 4 significant figures for that one, I would suggest you go with 2.617 rather than 2.7 anyway

I think that is correct. 153.6 has 4 sig figs, and 58.690 has 5 sig figs Between the two of them, 4 is the least amount of sig figs; since we're doing a division operation, the result will have the least amount of sig figs from either operand. In this case, that would be 4 sig figs
