Answer 2

13м78см+26м54см=4032см
5км300м-3км458м=184200см
9м38см-6м75см=2963см
3км608м+2км950м=6558000см

Answer 3

To perform the calculations, let's convert all the measurements to a consistent unit, such as centimeters (cm), and then perform the addition and subtraction operations.

1. 13m 78cm + 26m 54cm: Convert 13m 78cm to centimeters: 13m * 100cm/m + 78cm = 1300cm + 78cm = 1378cm Convert 26m 54cm to centimeters: 26m * 100cm/m + 54cm = 2600cm + 54cm = 2654cm Add the two measurements: 1378cm + 2654cm = 4032cm

Therefore, 13m 78cm + 26m 54cm = 4032cm.

2. 5km 300m - 3km 458m: Convert 5km 300m to meters: 5km * 1000m/km + 300m = 5000m + 300m = 5300m Convert 3km 458m to meters: 3km * 1000m/km + 458m = 3000m + 458m = 3458m Subtract the two measurements: 5300m - 3458m = 1842m

Therefore, 5km 300m - 3km 458m = 1842m.

3. 9m 38cm - 6m 75cm: Convert 9m 38cm to centimeters: 9m * 100cm/m + 38cm = 900cm + 38cm = 938cm Convert 6m 75cm to centimeters: 6m * 100cm/m + 75cm = 600cm + 75cm = 675cm Subtract the two measurements: 938cm - 675cm = 263cm

Therefore, 9m 38cm - 6m 75cm = 263cm.

4. 3km 608m + 2km 950m: Convert 3km 608m to meters: 3km * 1000m/km + 608m = 3000m + 608m = 3608m Convert 2km 950m to meters: 2km * 1000m/km + 950m = 2000m + 950m = 2950m Add the two measurements: 3608m + 2950m = 6558m

Therefore, 3km 608m + 2km 950m = 6558m.

So, the calculations are as follows: 13m 78cm + 26m 54cm = 4032cm 5km 300m - 3km 458m = 1842m 9m 38cm - 6m 75cm = 263cm 3km 608m + 2km 950m = 6558m
