Answer 3

To solve these arithmetic expressions, let's convert the measurements to a common unit (centimeters) and perform the calculations:

1 dm - 3 cm: 1 dm is equal to 10 cm, so we have: 10 cm - 3 cm = 7 cm

1 dm + 60 cm: 1 dm is equal to 10 cm, so we have: 10 cm + 60 cm = 70 cm

7 cm - 1 mm: 1 cm is equal to 10 mm, so we have: 7 cm - 1 mm = 7 cm - 0.1 cm = 6.9 cm

1 dm + 9 cm: 1 dm is equal to 10 cm, so we have: 10 cm + 9 cm = 19 cm

Therefore, the results are: 1 dm - 3 cm = 7 cm 1 dm + 60 cm = 70 cm 7 cm - 1 mm = 6.9 cm 1 dm + 9 cm = 19 cm
