7) 42 inches is 3 feet and 6 inches so she is not tall enough to go on the ride.
8) 1.72 meters is 172 centimeters so Alicia's mother is taller.
9) 1 pound=16 ounces so 4 pounds would be 64 ounces because 16×4=64.
10) 30 ounces=1 pound 14 ounces so the chunk of cheddar cheese is heavier.
hope this helped
