a) Converting all the lengths to kilometers, the longest to the shortest lengths are 6.3 km, 6.29 km, 6.25 km, and 6.24 km.
b) The longest to shortest lengths are 9.2 km, 9.1 km, 9,09 km, and 9.03 km.
Lengths can be converted from one unit to another by division or multiplication.
a) 6.25 km 6,240 m 6.3 km 6,290 m
We know that 1 kilometer = 1,000 m
Thus, converting all the values to kilometers:
6.25 km
6.24 km (6,240/1,000)
6.3 km
6.29 km (6,290/1,000)
Thus, ordering from longest to shortest:
6.3 km, 6.29 km, 6.25 km, 6.24 km
b) 9.03 km 9,100 m 9,090 m 92,000 cm
We know that 1 kilometer = 1,000 m and 100,000 cm = 1 kilometer
Thus, converting all the values to kilometers:
9.03 km
9.1 km (9,100 m/1,000)
9.09 km (9,090 m/1,000)
9.2 km (920,000 cm/100,000) = km
Thus, ordering from longest to shortest:
9.2 km, 9.1 km, 9,09 km, and 9.03 km
Complete Question:
Write the following lengths in order from longest to shortest:
a) 6.25 km 6,240 m 6.3 km 6,290 m
b) 9.03 km 9,100 m 9,090 m 920,000 cm
