Final answer:
Paul saves 1/4 of his weekly earnings of $56.24 for savings and spends 2/3 on clothes and school supplies. Hence, 1/4 is the fraction set aside for savings, and 2/3 is the fraction used for expenses.
Step-by-step explanation:
To determine the fractions of Paul's earnings that he sets aside for savings, clothes, and school supplies, we first need to calculate the amount he saves and spends. Paul saves 1/4 of his earnings, so the fraction he saves is 1/4. He spends 2/3 of his earnings on clothes and school supplies, so the fraction he spends is 2/3. Therefore, the fraction of his earnings that Paul sets aside for savings is 1/4, the fraction he spends on clothes and school supplies is 2/3, and the remaining fraction is the amount he has left over.
