Final answer:
Angelina can make 30 purses from the 10 yards of fabric by dividing the total yards of fabric by the fabric required for one purse.
Step-by-step explanation:
Angelina has 10 yards of fabric and needs ⅓ yard of fabric for each purse. To determine how many purses she can make, divide the total amount of fabric by the amount needed for one purse.
The calculation you'd perform is 10 yards ÷ ⅓ yard per purse. ⅓ yard is equivalent to 0.3333 when expressed as a decimal, so the division would look like this: 10 ÷ 0.3333.
When you complete this division, the result is 30. Therefore, Angelina can make 30 purses from the 10 yards of fabric she has.
