GaryK [48]

Answer:

The fraction is 2/5 of one gold bar.

Step-by-step explanation:

The king's ship sank with 8 gold bars aboard. Captain Nemo helped the King to find them and the king paid Captain Nemo 4/5 of one bar for finding the gold.

Let one gold bar be g.

This means the king paid Captain Memo 4/5 × g = 4g/5

The captain gave 1/2 of his gold to charity. This means that Captain Memo gave 1/2 of his 4g/5 gold bar to charity.

This amount that Captain Memo gave for charity would be

1/2 × 4g/5 = 4g / 10 = 2g/5

The fraction of a bar that went for charity would be

This amount that Captain Memo gave for charity would be /one gold bar. It becomes

2g/5 ÷ g = 2g/5 × 1/g

The g cancels out. Therefore,

The fraction is 2/5 of one gold bar.
