Answer:
The capacity of a car’s fuel tank is 8 pints.
Explanation:
We know that
1 gallon = 4 quarts
1 quart = 2 pints
First convert gallons into quarts.
20 gallons / 20 pints = (20 x 4) quarts / 20 pints
= 80 quarts / 20 pints
Convert quarts into pints.
= (80 x 2) pints / 20 pints
= 160 pints / 20 pints
= 8 pints

First convert quart into pints.
1 cup / 1 quart = 1 cup / (1 x 2) pints
= 1 cup / 2 pints
Next convert pints into cups.
1 cup / (2 x 2) cups = 1 cup / 4 cups
= 1/4 cups

Order from greatest capacity to least capacity. (Lesson 15.3)

1 gallon = 2 quarts
Convert quart into pints
14 quart = 14 x 2 pints = 28 pints
Convert gallons into pints
2 gallons = 2 x 4 x 2 pints = 16 pints
14qt > 2gal > 6pt

Question 51.

• The veterinarian at City Zoo keeps track of how much water each animal drinks in a period of time. Decide which animal drinks the greatest amount of water and fill in the blank.
  
  
  The ___________ drinks the greatest amount of water.
  Answer:
  The elephant drinks the greatest amount of water.
  Explanation:
  We know that 1 pint is equal to 2 cups.
  1 quarts is equal to 2 pints.
  1 gallon is equal to 4 quarts.
• The elephant drinks 20 one – gallon containers and 20 one – quart containers.
  20/4 = 5 gallons
  20 gallons + 5 gallons = 25 gallons
  The elephant drinks 25 gallons of water.
• The lion drinks 40 one – quarts containers and 3 one – gallon containers.
  40/4 = 10 gallons
  10 gallons + 3 gallons = 13 gallons
  The lion drinks 13 gallons of water.
• The Giraffe drinks 20 one – quart containers and 5 one – gallon containers.
  20/4 = 5 gallons
  5 gallons + 5 gallons = 10 gallons
  The giraffe drinks 10 gallons of water.
• The zebra drinks 3 one – gallon containers and 3 one – quart containers.
  3 gallons and 3 quarts is slightly greater than 3 gallons.
