1. 10 cm: 1 dm
Ans: reduces
2. 3 ft:3 yd
enlarges
3. 5 km: 5 m
enlarges
4. 1760 yd: 5280 ft
reduces

Answer 1

Think about what the size actually represents in meters. Whats the amount of meters 10 cm represents? And 1dm?

Just calculate everything to meters and see if the length is bigger/smaller/equal.
