7000m+120hm=….km
45dam-120dm=…. mm
18m+100dm-48cm=…. cm
5km-415m-8000cm=…. m

Jawaban:

1. 19 km

2. 938.000 mm

3. 2752 cm

4. 4505 m

Jawaban:

1.) 7.000 m + 120 hm

= 7 + 12 = 15 km

( 7.000 ÷ 1.000 = 7 km )

( 120 ÷ 10 = 12 km )

2.) 45 dam – 120 dm =

450.000 – 120.000 = 330.000 mm

( 45 × 10.000 = 450.000 mm )

( 120 × 100 = 120.000 mm )

3.) 18 km + 100 dm – 48 cm

= 1.800.000 + 1.000 – 48

= 1.801.000 – 48

= 1.800.952 cm

( 18 × 100.000 = 1.800.000 cm )

( 100 × 10 = 1.000 cm )

4.) 5 km – 415 m – 8.000 cm

= 5.000 – 415 – 80

= 4.505 m

( 5 × 1.000 = 5.000 m )

( 8.000 ÷ 100 = 80 m )
