1. 1.750dam

2. 1.550m

3. 525cm

Penjelasan dengan langkah-langkah:

a. 15km + 25hm

= (15 × 100)dam + (25 × 10)dam

= 1500dam + 250dam

= 1.750dam

b. 1,75km – 20dam

= (1, 75 × 1000)m – (20 × 10)m

= 1.750m – 200m

= 1.550m

c. 45dm + 750mm

= (45 × 10)cm + (750 : 10)cm

= 450cm + 75 cm

= 525cm
