Question

Sort the following in the ascending order of length (place the smallest measure on the top).

• A. 5 km
• B. 300 cm
• C. 2 m
• D. 20 mm
• E. 30 m

Answer 1

To compare, we will first convert all the measurements to the same unit.
5 km = 5,00,000 cm
300 cm = 300 cm
2 m = 200 cm
20 mm = 2 cm
30 m = 3,000 cm
So the lengths in ascending order is 20 mm < 2 m < 300 cm < 30 m < 5 km
