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.

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
