Jawab:

a. 1750 dam

e. 2.475 km

f. 293 dm

i. 595 dam

j. 250 m

Penjelasan dengan langkah-langkah:

a. 15 km + 25 hm

= 1.500 dam + 250 dam

= 1.750 dam

e. 2.500 km – 2.500 dam

= 2.500 km – 25 km

= 2.475 km

f. 20 m + 120 dm – 270 cm

= 200 dm + 120 dm – 27 dm

= 293 dm

i. 7 km – 12 hm + 150 m

= 700 dam – 120 dam + 15 dam

= 595 dam

j. 6,2 km – 22 hm – 3.750 m

= 6.200 m – 2.200 m – 3.750 m

= 250 m

Penjelasan dengan langkah-langkah:

A.) 15 km + 25 hm = … dam

= (15 x 100) + (25 x 10)

= 1500 + 250

= 1750 dam

E.) 2500 km – 2500 dam = … km

= 2500 – (2500 : 100)

= 2500 – 25

= 2475 km

F.) 20 m + 120 dm – 270 cm = … dm

= (20 x 10) + 120 – (270 : 10)

= 200 + 120 – 27

= 293 dm

I.) 75 km – 12 hm + 150 m = … dam

= (75 x 100) – (12 x 10) + (150 : 10)

= 7500 – 120 + 15

= 7395 dam

J.) 6,2 km – 22 hm – 3750 m = … m

= (6,2 x 1000) – (22 x 100) – 3750

= 6200 – 2200 – 3750

= 250 m
