After the first 1/8 died, only 7/8 were left

3/5 of those died, meaning 3/5 * 7/8 of the original number died

1/8 = 5/40

3/5 * 7/8 = 21/40

So, 26/40 = 13/20 of the fish died

Never buy fish from a farm. Farmed fish is yuucky. Good fish comes from the ocean.

lets start with 40 fish

the first week 5 die so we have 35 which is 7/8 of original

after first week 7/8 or 35 remain

then in weeks two and three 3/5* 35 = 21 die so we are left with 35 -21 = 14 fish

so in those first three weeks 26 died

26/40 = 13/20
