Answer 3

To perform the subtraction of the two given measurements, we need to convert them into the same unit. Let's convert them both into centimeters (cm) and then perform the subtraction:

1 meter (m) = 100 centimeters (cm) 1 decimeter (dm) = 10 centimeters (cm)

First, let's convert the second measurement, 2m 6dm 9cm, into centimeters:

2 meters = 2 * 100 = 200 cm 6 decimeters = 6 * 10 = 60 cm 9 centimeters = 9 cm

Total = 200 cm + 60 cm + 9 cm = 269 cm

Now, let's subtract 4m 7cm from 269 cm:

269 cm - 4 m 7 cm

1 meter = 100 cm

4 m = 4 * 100 cm = 400 cm 7 cm = 7 cm

Total = 400 cm + 7 cm = 407 cm

Finally, the result is 407 centimeters.
