Final answer:
After Marilyn drank 1/8 of a gallon and Kelly drank 1/4 of a gallon from the initial 5/8 gallon of lemonade, the remaining amount in the pitcher is 1/4 gallon.
Step-by-step explanation:
To calculate how much lemonade is left in the pitcher after Marilyn and Kelly drank some, we need to subtract the amounts they drank from the initial amount. Marilyn started with 5/8 of a gallon of lemonade. Marilyn drank 1/8 of a gallon, and Kelly drank 1/4 of a gallon. Remember that 1/4 is equivalent to 2/8 when finding a common denominator.
Here are the steps to calculate the remaining lemonade in the pitcher:
- Convert each fraction to have a common denominator, if necessary.
- Subtract the fractions to find out how much lemonade is left.
Step 1: Convert 1/4 to an equivalent fraction with a denominator of 8:
1/4 = 2/8
Step 2: Subtract the fractions from the initial amount:
Initial amount = 5/8 gallon
Marilyn drank = 1/8 gallon
Kelly drank = 2/8 gallon
Remaining lemonade = 5/8 - (1/8 + 2/8)
Remaining lemonade = 5/8 - 3/8
Remaining lemonade = 2/8 gallon, which simplifies to 1/4 gallon.
There is 1/4 gallon of lemonade left in the pitcher.
