How many liters are equivalent to 250 milliliters? (Note that 1 liter = 1000 milliliters)

• 0.25 liter

• 2 500 liters

• 0.025 liter

• 2.5 liters

Answer explanation

1 liter = 1,000 milliliters

Liters are larger than milliliters, so the number of liters will be less than the number of milliliters. Divide the number of milliliters by 1,000 or 10³.

250 ÷ 1,000 = 0.25 because dividing by 10³ moves the decimal point three places to the left.

A football player runs for 13 1/2 yards. How many feet does he run? (1 yard = 3 feet)

• 4 1/2

• 400 1/2

• 40 1/2

• 4,000 1/2

Answer explanation

1 yard = 3 feet

Feet are smaller than yards so the number of feet will be greater than the number of yards. Multiply the number of yards by 3.

You may break apart 13 1/2 yards and multiply the whole number and fraction separately by 3, then combine the products to find the number of feet.

13 x 3 = 39;

1/2 x 3 = 3/2 or 1 1/2

Add the answers:

39 + 1 1/2 = 40 1/2

Jillian makes 10 1/2 gallons of lemonade to sell at her store in 1-quart bottles. How many quarts of lemonade can she make? (1 gallon = 4 quarts)

• 4.2 quarts

• 42 quarts

• 2. 625 quarts

• 26. 25 quarts

Answer explanation

1 gallon = 4 quarts

Quarts are smaller than gallons, so the number of quarts will be greater than the number of gallons.

Multiply the number of gallons by 4.

10 x 4 = 40, ½ x 4 = 2

Add the answers:

40 + 2= 42 quarts

How many kilogram/s is/are equivalent to 450 grams? (1 kilogram = 1 000 grams)

• 45 kilograms

• 4.5 kilograms

• 0.045 kilogram

• 0.45 kilogram

Answer explanation

1 kilogram= 1,000 grams Kilograms are larger than grams, so the number of kilograms will be less than the number of grams. Divide the number of grams by 1,000 or 10³.

450 ÷ 1,000 = 0.45 because dividing by 10³ moves the decimal point three places to the left.

450 grams = 0.45 kilogram

How many millimeters are in 118 meters? (1 meter= 1 000 millimeters)

• 0.0118 millimeter

• 0.118 millimeter

• 118,000 millimeters

• 1,180,000 millimeters

A mining company digs 75 kilograms of silver. They plan to use 1 gram of silver in each special coin they make. How many grams are equivalent to 75 kilograms? (1 kilogram = 1 000 grams)

• 75,000 grams

• 7,500 grams

• 0.75 grams

• 0.075 grams

Five measurements are shown below. Select two true equations based on the measurements given.

300 millimeters 30 meters 3,000 meters

3 kilometers 3,000 centimeters

• 30 meters = 3,000 centimeters

• 3 kilometers = 3,000 meters

• 300 millimeters = 3,000 centimeters

• 3 kilometers = 3,000 centimeters
