Final answer:
Mrs. Walsh used 1 and 1/8 pounds of potatoes to make fries. This was determined by multiplying the total weight of the potatoes (5 and 5/8 pounds) by 1/5.
Step-by-step explanation:
The question involves calculating the quantity of potatoes Mrs. Walsh used to make fries. She initially has 5 and 5/8 pounds of potatoes and uses 1/5 of that amount.
To find the weight of potatoes used, we need to multiply the total weight by 1/5.
First, convert 5 and 5/8 pounds to an improper fraction: (5 × 8) + 5 = 45/8 pounds of potatoes.
Next, we multiply this by 1/5 to find the weight used for fries:
(45/8) × (1/5) = 45/40
= 9/8 pounds
9/8 pounds can be simplified to 1 and 1/8 pounds.
Therefore, Mrs. Walsh used 1 and 1/8 pounds of potatoes to make fries.
