Question

1. which shows a correct comparison? a 5 milliliters > 50 liters b 2 liters < 200 milliliters c 100 liters < 1,000 milliliters d 3,200 milliliters > 3 liters

Explanation:

Step1: Recall unit conversion (1 liter = 1000 milliliters)

For option A: Convert 50 liters to milliliters. $50 \text{ liters} = 50\times1000 = 50000 \text{ milliliters}$. So 5 milliliters < 50000 milliliters. A is wrong.

Step2: Convert 2 liters to milliliters

$2 \text{ liters} = 2\times1000 = 2000 \text{ milliliters}$. 2000 milliliters > 200 milliliters. B is wrong.

Step3: Convert 100 liters to milliliters

$100 \text{ liters} = 100\times1000 = 100000 \text{ milliliters}$. 100000 milliliters > 1000 milliliters. C is wrong.

Step4: Convert 3 liters to milliliters

$3 \text{ liters} = 3\times1000 = 3000 \text{ milliliters}$. 3200 milliliters > 3000 milliliters. D is correct.

Answer:

D. 3,200 milliliters > 3 liters
