a man spends 4/5of his money, what fraction of his money is left?

(5/5) - (4/5) = ?

4/5 + 1/5 = 5/5 = all of it

To find out what fraction of his money is left, we need to subtract the portion he spent from the whole amount.

Let's say the man initially had 1 whole unit of money. He spends 4/5 of his money, which means he uses 4/5 of the total amount.

To calculate the remaining amount, we can subtract 4/5 from 1:

1 - 4/5 = 5/5 - 4/5 = 1/5

So, the man has 1/5 of his money left.
