3 hm + 7 m + 4 cm =….mm

Jawaban:

1. 307.040 mm

2. 2.370 m

3. 7.342 m

Penjelasan dengan langkah-langkah:

1. 3hm = 3×100.000 = 300.000 mm

7m = 7×1.000 = 7.000 mm

4cm = 4×10 = 40 mm

300.000+7000+40 mm

= 307.040 mm

2. 2km = 2×1.000 = 2000 m

3hm = 3×100 = 300 m

7 dam = 7×10 = 70 m

2000+300+70 m

= 2.370 m

3. 7km = 7×1.000 = 7.000 m

34 dam = 34×10 = 340 m

200 cm = 200÷100 = 2 m

7.000+340+2 m

= 7.342 m
