Selesaikan soal berikut: a.15000m+10000m=....dam b.250hm+100hm=.....km c.15000mm+25000dm=....dam d.875000mm-42500dm=....m e.12500km+1500hm=......cm f.55000mm=..

a. 15000+10000=2500dam,
b. 250+100=35km
c. 15000=1.5,25000=250
250+1. 5=261.5dam
d. 875m-4250m=-3375m
e. 1250000000+15000000=...m
f. 55000=5500
g. 387000=387dam
h. 3000+200=3200dam
i. 40-15=25m
j. 25cm=250mm

a.15000 m+10000 m=15.000÷10 +10000÷10
=1500 dam+1000 dam
=2500 dam
b.250 hm+100 hm=250÷10+100÷10
=25 km+10 km
=35 km
c.15000 mm+25.000 dm=15000÷10000+25000÷100
=1,5 dam+250 dam
=251,5 dam
d.875000 mm-42500 dm=87500÷1000-42500÷10
=875 m-4250 m
=-3375 m
e.12500 km+1500 hm
=12500÷10000+1500÷1000
=12,5 cm+1,5 cm
=14 cm
f.55000 mm=55000÷10
=5500 cm
g.387000 cm=387000÷1000
=387 dam
h.3 km+2 hm=3×100+2×10
=300+20
=320 dam
i.4 dam -15 m=4×10-15
=40 m-15 m
=25 m
j.10 cm+15 cm=10×10+15×10
=100+150
=250 mm

Semoga membantu
