1. 15 km + 15 dm =…hm
2. 310 m + 25 cm =…km
3. 55 dm + 55 cm =…mm
4. 1250 cm + 25 cm =…dam
5. 115 cm + 25 hm =…m
Boleh bantu jawab? kalo bisa sekalian dengan caranya yaa…makasihhh
Jawaban:
caranya ada digambar
1. 15 km + 15 dm = …. hm
= (15 × 10) + ( 15 ÷ 1.000)
= 150 + 0,015
= 150,015 hm
2. 310 m + 25 cm = … km
= (310 ÷ 1000) + (25 ÷ 100.000)
= 0,31 + 0,00025
= 0,31025 km
3. 55 dm + 55 cm = …mm
= ( 55 × 100) + (55 × 10)
= 5.500 + 550
= 6.050 mm
4. 1.250 cm + 25 cm = …dam
= (1.250 ÷ 1000) + ( 25 ÷ 1000)
= 1,25 + 0,025
= 1,275 dam
5. 115 cm + 25 hm = … m
= ( 115 ÷ 100) + ( 25 × 100)
= 1,15 + 2.500
= 2.501,15 m
