The amount of material left in radioactive decay is an exponential function. Therefore, the way you solve this is to write it as an exponential function; for example:
f = e-kt, where "f" is the fraction remaining after a certain time, "t" is the time in any unit you choose (for example, years), and "k" is a constant you have to find out. Replace the numbers you know (for t = 1600 years, f = 1/2, since 1/2 of the original remains), and solve for "k".
Then, write the equation again, this time with the constant "k" you figured out before, and the time (365 years). This will give you the fraction left after that amount of time.

How many grams is 1600 mg?
1,000 mg = 1 gram 1,600 mg = (1,600 / 1,000) = 1.6grams
1600 mg equals how many grams?
1,000 mg = 1 gram 1,600 mg = (1,600 / 1,000) = 1.6grams
If Ra-226 had a f life of 1600 years and you have 20 grams how much will be left in 3200 years?
After 1600 years, half of the 20 grams of Ra-226 will remain, so 10 grams will be left. After another 1600 years (3200 years total), half of the remaining 10 grams will remain, resulting in 5 grams of Ra-226 left.
How many grams of radium-226 will remain from 5 grams after 365 years if the half life of radium 226 is 1600?
The question, as posed cannot be answered because you have not stated the units for the half-life. Some things have half lives of millions of years while others have half-lives measured in micro-seconds. Fortunately, Wikipedia came to my rescue and the half-life is 1600 years (approx). The answer is approx 4.3 grams.
