Pertanyaan

a. 49 dm - 1200 m = ......... cm
b. 2,35 m + 473 dm = ....... cm
c. 27 hm + 13 dam + 8 m = ....... m

Answer 1

a 490 cm - 120000 cm = - 119510 cm
b 235 cm + 4730 cm = 4965 cm
c 270000 + 13000 + 800 = 283800 cm

Answer 2

a.49*10=490
1200*100=120000
490-120000=-119510cm
b.2,35*100=235
473*10=4730
235+4730=4965cm
c.27*100=2700
13*10=130
8*1=8
2700+130+8=2838m
