Tolong di jawab ya! 58 km + 9 hm = ...... dam 731 dm + 14 cm = ...... mm 145 m + 4.800 dm = ...... dam 856 hm - 15 km = ....... m 972 m + 5.270 mm = ....... cm

58 km + 9 hm
= ( 58 × 100 ) + ( 9 × 10)
= 5.800 + 90
= 5.890 dam

731 dm + 14 cm
= ( 731 × 100 ) + ( 14 × 10)
= 73100 + 140
= 73.240 mm

145 m + 4.800 dm
= ( 145 ÷ 10 ) + (4.800 ÷ 100)
= 14,5 + 48
= 62,5 dam

856 hm - 15 km
= ( 856 × 100) - ( 15 × 1.000)
= 85.600 - 15.000
= 70.600 m

972 m + 5.270 mm
= ( 972 × 100) + (5.270 ÷ 10)
= 97.200 + 527
= 97.727 cm

1.) 5890
2.)73240
3.)62,5
4.)70.600
5.)97727
maaf kalo ada yang salah...di periksaa lagii yahh
