Sample A

Rita wanted to make pancakes for breakfast. She had pancake mix but needed to pick up some other

ingredients at the store. She bought a one-half gallon of milk and a 32-ounce container of maple syrup.

What are the metric equivalents to the two ingredients that Rita bought at the store? Use milliliters or

liters in your answer.

1 –

gallon of milk = 64 fluid ounces of milk

(Remember, 1 fluid ounce = 30 mL, and 1,000 milliliters = 1 liter)

64 x 30 mL = 1,920 mL = 1.92 liters

So, 1 –

gallon of milk is equivalent to 1.92 liters of milk.

32 fluid ounces of maple syrup = 32 x 30 mL = 960 mL

So, 32 fluid ounces of maple syrup is equivalent to 960 mL of maple syrup.
