Question

23Km + 8Hm + 4Dm + 10m en m. =

185Km + 8Dm + 1820cm en Dm. =

18Hm – 4Dm + 80 m en Hm. =

Me pueden ayudar con estos 3 problemas PORFAVOR!

Answer 1

1Km = 1000m

23Km = 23*1000 = 23000m

1Hm = 100m

8Hm = 8*100 = 800m

1Dm = 10m

4Dm = 4*10 = 40m

por tanto:

23Km + 8Hm + 4Dm + 10m = 23000+800+40+10 = 23850m

1Km = 100Dm

185Km = 185*100 = 18500Dm

1Dm = 1000cm

1820cm = 1820/1000 = 1.82Dm

por tanto:

185Km + 8Dm + 1820cm = 18500 + 8 + 1.82 = 18509.82Dm

1Hm = 10Dm

4Dm = 4/10 = 0.4Hm

1Hm = 100m

80m = 80/100 = 0.8Hm

por tanto:

18Hm  - 4Dm + 80m = 18 - 0.4 + 0.8 = 18.4Hm
