Final answer:
Mrs. Anderson took 3 tubs of potato salad to the picnic and had 1 2/5 tubs left over. The leftovers were divided among 10 attendees. Each attendee received 72/25 ounces of potato salad.
Step-by-step explanation:
To solve this problem, we need to first determine how many tubs of potato salad were left over. Mrs. Anderson originally took 3 tubs of potato salad, and 1 2/5 of them were leftover. To find this amount, we can convert the mixed number 1 2/5 to an improper fraction. This is done by multiplying the whole number, 1, by the denominator, 5, and then adding the numerator, 2, resulting in 7/5.
Next, we subtract 7/5 from 3 to find the number of leftover tubs: 3 - 7/5 = 15/5 - 7/5 = 8/5. So, there were 8/5 tubs of potato salad left over. Finally, we divided the 8/5 tubs of potato salad evenly among the 10 attendees. To do this, we divide 8/5 by 10: (8/5) / 10 = 8/5 * 1/10 = 8/50 = 4/25. Therefore, each attendee received 4/25 of a tub of potato salad, and to convert this fraction to ounces, we multiply it by the size of each tub, which is 18 ounces, resulting in each attendee receiving 4/25 * 18 = 72/25 ounces of potato salad.
