Answer:
1st: 5 gal > 18 qt
2nd: 4.5 km < 5,000 m
Explanation:
1 gallon is equal to 4 quarts
Going by this logic, 5 gallons should be 20 quarts. Since it says 18, 5 gallons is more than it. So the answer is '>'.
1 kilometer is the same as 1000 meters
4.5 kilometers * 1000 = 4,500 meters
5000 meters / 1000 = 5km
So the answer should be '<' since 5,000m is greater than 4.5km.
