Penjelasan dengan langkah-langkah:

1. a. 27 m 45 cm = . . . cm

27 m = 27 × 100 = 2.700 cm

45 cm = 45 cm

= 2.745 cm

b. 4 m 50 cm = . . . cm

4 m = 4 × 100 = 400 m

50 cm = 50 cm

= 450 cm

c. 9 km 15 dam = . . . m

9 km = 9 × 1.000 = 9.000 m

15 dam = 15 × 10 = 150 m

= 9.150 m

d. 8 hm 370 m = . . . m

8 hm = 8 × 100 = 800 m

370 m = 370 m

= 1170 m

2. a. 3 hm + 7 m + 4 cm = . . . mm

= (3 × 100.000) + (7 × 1.000) + (4 × 10)

= 300.000 + 7.000 + 40

= 307.040 mm

b. 2 km + 3 hm + 7 dam = . . . m

= (2 × 1.000) + (3 × 100) + (7 × 10)

= 2.000 + 300 + 70

= 2370 m

c. 7 km + 34 dam + 200 cm = . . . m

= (7 × 1.000) + (34 × 10) + (200 ÷ 100)

= 7.000 + 340 + 2

= 7.342 m

d. 6 dam + 8 m + 2 dm = . . . cm

= (6 × 1.000) + (8 × 100) + (2 × 10)

= 6.000 + 800 + 2

= 6.802 cm

3. 4 m 50 cm = . . . cm

4 × 100 = 400 cm

50 cm = 50 cm

= 450 cm

Dibagi kepada 5 orang : Dina, Desi, Dini, Devi, Duma,

Ditanya? berapa cm setiap orang masing masing,

= 450 cm ÷ 5 = 90cm

jadi, setiap orang akan memperoleh 90cm panjang pita.
