the directions for lemonade say to put 2 cups of liquid concentrate into one gallon of water. if olivia only wants to make one pint of lemonade, how many fluid ounces of concentrate should she put?
2 cups = 16 fluid ounces
1 gallon = 128 fluid ounces
1 pint = 16 fluid ounces
x/16 = 16/128
Solve for x.
1 gallon = 16 cups
The directions make 18 cups.
1 pint = 2 cups
Solve this proportion.
2/18 = x/2
18x = 4
x = 0.222 cups of concentrate
To determine how many fluid ounces of concentrate Olivia should put, we can start by finding the ratio of concentrate to water given in the directions.
From the instructions, it states that 2 cups of liquid concentrate are used for one gallon of water.
To convert gallons to pints, we know that there are 8 pints in one gallon. Therefore, for one pint of lemonade, Olivia needs 1/8th (1/8) of the amount of concentrate required for a gallon.
To calculate how many fluid ounces of concentrate Olivia needs, we can use the following conversion: 1 cup = 8 fluid ounces.
Since Olivia only needs 1/8th of the total amount of concentrate required for a gallon, we can calculate it as follows:
2 cups * (1/8) = 2/8 = 1/4 cup
To convert the 1/4 cup to fluid ounces, we can multiply by 8:
1/4 cup * 8 fluid ounces/cup = 2 fluid ounces.
Therefore, Olivia should put 2 fluid ounces of concentrate to make one pint of lemonade.
