### Rounding vs. Multiplying

If you are solving for an empirical formula and the ratios are not whole numbers, when do you round and when do you multiply?

Ex. 1 C : 1.1 O : 1 N

Would you round 1.1 down or multiply by 10 to get an integer?

You would just round the 1.1 to 1. A lot of time numbers like that are probably just rounding errors.

I would say to round off when the decimal is between one point of different ex. 1.1 to 1, the others should probably be multiplied.

I would multiply to find another ratio if the decimal is more than .2 away from a whole number. So if I you had 1.1, I would just round down to 1.

My TA told us that rounding when the decimal was .1 or .2 was acceptable, while bigger numbers such as .3 are better multiplied. :D
