Answer 1

Răspuns:

a) 4 dm + 6 dm = 1m

b) 770 mm + 230 mm = 1 m

c) 9 dm + 10 cm = 1m

d) 80 cm + 2 dm = 1 m

e) 6 m + 10 dm + 300 cm = 100 dm

f) 9 dm + 10 cm + 2000 mm = 3 m

Explicație pas cu pas:

a) 4 dm + 6 dm = 10 dm = 1m

b) 770 mm + 230 mm = 1000 mm = 1 m

c) 9 dm + 10 cm = 9 dm + 1 dm = 10 dm = 1m

d) 80 cm + 2 dm = 8 dm + 2 dm = 10 dm = 1 m

e) 6 m + 10 dm + 300 cm = 60 dm + 10 dm + 30 dm = 100 dm

f) 9 dm + 10 cm + 2000 mm = 0,9 m + 0,1 m + 2 m = 3 m
