Jadyn Delacruz · Answer 1

24 coins

Step-by-step explanation:

Start:

first pirate - -> 1/2 coins

second pirate - -> 3/2 coins

Next:

first pirate - -> 1/2 + 3/4 = 5/4 coins

second pirate - -> 3/2 - 3/4 = 3/4 coins

Next:

first pirate - -> 5/4 - 5/8 = 5/8 coins

second pirate - -> 3/4 + 5/8 = 11/8 coins

So:

If 5/8 coins is 15, then 1/8 coins is 3, and 8/8 coins is 24 coins.
