Final answer:
To find out what fraction of Peter's money is left, add up the fractions he spent and subtract from 1 (whole). The fraction of money left is 1/24.
Step-by-step explanation:
To find out what fraction of Peter's money is left, we need to subtract the fractions he spent from 1 (whole). In this case, we can add up the fractions he spent: 1/3 + 1/2 + 1/8 = 8/24 + 12/24 + 3/24
= 23/24.
Now, to find the fraction that is left, we subtract 23/24 from 1, which gives us 1 - 23/24 = 1/24.
Therefore, 1/24 of Peter's money is left.
