Answer 3

To perform these subtractions, we need to make sure that all the units are the same. Let's convert all of them to meters:

2 km 20 m = (2 * 1000) m + 20 m = 2020 m 1 km 76 m = (1 * 1000) m + 76 m = 1076 m So, 2 km 20 m - 1 km 76 m = 2020 m - 1076 m = 944 m

3 km 5 dm = (3 * 1000) dm + (5 * 10) dm = 30050 dm 9 dm 3 cm = (9 * 10) dm + 3 cm = 93 dm + 3 cm = 930 cm + 3 cm = 933 cm So, 3 km 5 dm - 9 dm 3 cm = 30050 dm - 933 cm = 30050 dm - 9.33 m = 30040.67 dm

5 m = 5 m 3 dm 8 cm = 3 dm + 8 cm = 30 cm + 8 cm = 38 cm So, 5 m - 3 dm 8 cm = 5 m - 0.38 m = 4.62 m

Therefore, the results of the subtractions are:

• 2 km 20 m - 1 km 76 m = 944 m
• 3 km 5 dm - 9 dm 3 cm = 30040.67 dm
• 5 m - 3 dm 8 cm = 4.62 m
