Final answer:
To find out how much ice cream each guest will eat, divide 9.8 gallons of ice cream by the 27 guests, after converting gallons to cups, and then convert the per person result back to gallons if necessary.
Step-by-step explanation:
To determine the amount of ice cream each person will eat at Brenda's birthday party, we need to divide the total amount of ice cream by the number of guests. Brenda has 9.8 gallons of ice cream and there will be 27 guests. So, we perform the division: 9.8 gallons ÷ 27 guests.
First, we convert the gallons to a smaller unit (cups, for example) to make it easier to divide and then convert back to gallons for the final answer. There are 16 cups in a gallon, so 9.8 gallons is equal to 9.8 × 16 cups. Multiplying this out gives us 156.8 cups of ice cream.
Now, we divide 156.8 cups by 27 guests to find out how many cups each guest will get and then convert back to gallons if necessary.
Step-by-step:
- Convert gallons to cups: 9.8 gallons × 16 cups/gallon = 156.8 cups
- Divide by the number of guests: 156.8 cups ÷ 27 guests
- Convert the per person amount back to gallons if needed by dividing by 16
