Question

- Вычислите. 5m 9 dm 8cm + 6m 3dm 8 cm 7m 2 dm 3 cm - 4m 6 dm 7 cm 6m 8cm + 1 m 2 dm 1 cm 3m 7 cm + 95 cm 9m - 4m 74 cm 12 dm + 4m​

Answer 1

5m 9 dm 8cm + 6m 3dm 8 cm = 11m 11dm 16cm = 12m 2dm 6cm

7m 2 dm 3 cm - 4m 6 dm 7 cm = 6m 11 dm 13 cm - 4m 6 dm 7 cm = 2m 5dm 6cm

6m 8cm + 1 m 2 dm 1 cm = 7m 2 dm 9 cm

3m 7 cm + 95 cm = 3m 7 cm + 9dm 5cm = 3m 9dm 12cm = 4m 2 cm

9m - 4m 74 cm = 5m - 74cm = 4m 9 dm 10 cm - 7dm 4cm = 4m 2dm 6cm

12 dm + 4m​ = 4m 12 dm = 5m 2 dm
