2. 9 km + 35 hm = … dam.

1. ubah semua kedalam bentuk dam

~ 9 km = 9 × 100 = 900 dam

~ 35 hm = 35 × 10 = 350 dam

jadi:

~ 900 dam + 350 dam = 1250 dam

2. ubah semua kedalam m

~ 2,05 km = 2,05 × 1.000 = 2.050 m

~ 150 dam = 150 × 10 = 1.500 m

jadi:

~ 2.050 – 1.500 = 550 m

3. ubah semua kedalam bentuk cm

~ 8 hm = 8 × 10.000 = 80.000 cm

~ 300 m = 300 × 100 = 30.000 cm

jadi:

~ 80.000–30.000 : 50.000 cm

4? ubah semua kedalam bentuk m

~ 15 dam = 15 × 10 = 150 m

~ 250 dm = 250:10 = 25 m

jadi:

~ 150–25 = 125 m

semoga membantu ya:)

Jawaban:

1. 1.250 dam

2. 550 m

3. 50.000 cm

4. 175 m

Penjelasan dengan langkah-langkah:

1. 9 km + 35 hm = ….dam

9 km = 9 × 100

= 900 dam

35 hm = 35 × 10

= 350 dam

900 dam + 350 dam

= 1.250 dam

2. 2,05 km – 150 dam =….m

2,05 km = 2,05 × 1.000

= 2.050 m

150 dam = 150 × 10

= 1.500 m

2.050 m – 1.500 m

= 550 m

3. 8 hm – 300 m =….cm

8 hm = 8 × 10.000

= 80.000 cm

300 m = 300 × 100

= 30.000 cm

80.000 cm – 30.000 cm

= 50.000 cm

4. 15 dam + 250 dm =…m

15 dam = 15 × 10

= 150 m

250 dm = 250 : 10

= 25 m

150 m + 25 m

= 175 m
