then after that, 3/5 of the remaining died, so 2/5 lived, so we get:

7/20 lived, so 13/20 died.

Answer 46

With these types of problems, its important to keep track of what the numbers we are getting represent. That is where I messed up earlier. So lets start from the beginning.

In the first week, 1/8 of the fish died. That means that:
\[1-\frac{1}{8} = \frac{7}{8}\]lived.
Now, in the next two weeks, 3/5 of the fish left also died. That means:
\[1-\frac{3}{5} = \frac{2}{5}\]of the 7/8 left alive from the first week survied the next two weeks. This gives us:
\[\frac{7}{8}*\frac{2}{5} = \frac{14}{40} = \frac{7}{20}\] of the fish lived after the last 2 weeks.
This also means that:
\[1-\frac{7}{20} =\frac{13}{20}\]died after the last two weeks. You dont really specify which answer you are looking for in your question, so it could be any one of those 2 answers.
