Final answer:
The boy spent 11/15 of his money on sweets and records combined and has 4/15 of his money remaining.
Step-by-step explanation:
The question asks about a boy who spent a fraction of his money on sweets and another fraction on records, and we need to calculate two results: the total fraction of money he spent and the fraction he has remaining.
Part a)
To find the total fraction of money spent, we add the fractions of money spent on sweets and on records together:
2/5 (sweets) + 1/3 (records) = 6/15 + 5/15 = 11/15.
The boy spent 11/15 of his money.
Part b)
To find the fraction of money remaining, we subtract the total fraction spent from the whole (which is 1):
1 - 11/15 (spent) = 4/15 (remaining).
The boy has 4/15 of his money remaining.
