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

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

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

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

3m 7 cm + 95 cm = 3m 7cm + 9dm 5cm = 3m 16dm 5cm = 4m 6dm 5cm

9m - 4m 74 dm 12 cm + 4m​ = 9m - 11m 5dm 2cm + 4m = 8m 9dm 10cm - 11m 5dm 2cm + 4m = -3m 4dm 8cm + 4m = 1m 4dm 8cm

Ответ:

34m 9dm 4cm

Пошаговое объяснение:

598+4200+60+24-2400-60-56+300+20+7+95+ +900-400-74-120+400 = 3494cm

= 34m 9dm 4cm
