Science Homework Help. Need help with SI units, scientific notation if appropriate

Answer the following in the proper SI units, scientific notation if appropriate. Assume exactly 365 days per year. 

1.) 124.1 g  +35 mg=?

2.)  23m^2 + 345.7 ha=? 

3.) 6.6079 x 10^15 cm^3 / 6km^2 

Additional question: for these questions… how do we know what unit to convert to? I.e., in question 1 there is mg and grams? does it matter which unit to convert to or can we do either?
