The answer for your question is 2.25 (decimal), or 2 1/4.
I got this answer by changing both 3/4 to 9/6, which 3/4 = 0.75, and 9/6 = 1.50.
Now, you add both 0.75 and 1.50 together, which gives you 2.25, which is the answer that I got.
Hope this helped!

Well, I'll answer this problem:
<span>mercury-197 has a half life of about 64 hours. After 288 hours about how many miligrams of a 750mg sample
According to this site:
http://www.1728.org/halflife.htm
Ending Amount = Beginning amount / 2^n
where "n" is the number of half-lives (elapsed time / half-life)
</span>"n" =288 / 64 = 4.5
<span>Ending Amount = 750 mg / 2^4.5
</span>Ending Amount = 750 mg / <span><span>22.627416998
