1)71,2 hm+12 km +100 dam=….dam

Jawaban:

1 ) 8.420 dam

2 ) 9.426 dm

3 ) 15.775 dm

4 ) 976,5 dam

Penjelasan dengan langkah-langkah:

✒ 1.

71,2 hm + 12 km + 100 dam = …dam

71,2 × 10 = 712 dam

12 × 100 = 1.200 dam

712 + 1.200 + 100 = 2.012 dam ✅

✒ 2.

66,75 dam + 25,1 m + 250 dam = …dm

66,75 × 100 = 6.675 dm

25,1 × 10 = 251 dm

250 × 100 = 2.500 dm

6.675 + 251 + 2.500 = 9.426 dm ✅

✒ 3.

1,725 km – 1,475 hm = …dm

1,725 × 10.000 = 17.250 dm

1,475 × 1.000 = 1.475 dm

17.250 – 1.475 = 15.775 dm ✅

✒ 4.

114,75 hm – 21 dam – 150 dam = …dam

114,75 × 10 = 1.147,5 dam

1.147 – 21 – 150 =976,5 ✅

Penjelasan dengan langkah-langkah:

1. 71,2hm + 12km + 100dam = ….. dam

(71,2×10) + (12×100) + 100

=712 dam + 1.200 dam + 100 dam

= 2.012 dam

2.66,75dam + 25,1m + 250 dam = …. dm

(66,75×100) + (25,1×10) + (250×100)

=6.675 dm + 251 dm + 25.000 dm

= 31.926 dm

3. 1,725 km – 1,475hm = … dm

(1,725×10.000) – (1,475×1.000)

=17.250 dm + 1.475 dm

= 15.775 dm

4. 114,75 hm – 21 dam – 150 dam =…. dam

(114,75×10) – 21- 150

=1.147,5 dam – 21 dam – 150 dam

= 976,5 dam
