Answer 2

Răspuns:

Explicație pas cu pas:

a ) 1 hm + 1 dam = ? m

1 hm = 1 × 100 m = 100 m

1 dam = 1 × 10 m = 10 m

100 m + 10 m = 110 m

b ) 3 km + 3 hm = ? hm

3 km = 3 × 10 hm = 30 hm

30 hm + 3 hm = 33 hm

c ) 2 m + 2 cm = ? mm

2 m = 2 × 1000 mm = 2000 mm

2 cm = 2 × 10 mm = 20 mm

2000 mm + 20 mm = 2020 mm

d ) 8 dam - 3 m = ? m

8 dam = 8 × 10 m = 80 m

80 m - 3 m = 77 m
