Question

Efetue as operações, dando a resposta em metros:
a) 0,630km + 8000cm :
b) 12200cm + 0,060km + 40000mm :
c) 0,400km + 6000cm :
d) 6000mm + 1,2km + 1dam :

Answer 1

A/ 0,630km = 630m, 8000cm = 80m. 630m + 80m = 710m
B/ 12200cm = 122m, 0,060km = 60m, 40000mm = 40m. 122m + 60m + 40m = 222m
C/ 0,400km = 400m, 6000cm = 60m. 400m + 60m = 460m
D/ 6000mm = 6m, 1,2km = 1200m, 1dam = 10m. 6m + 1200m + 10m = 1216m.

Answer 2

A) 0,630km+8000cm
0,630km x 1000=630m
8000cm ÷100= 80m
630m+80m= 710m

B) 12200cm + 0,060km + 40000mm
12200cm ÷ 100= 122m
0,060km x 1000= 60m
40000 ÷ 1000=40m
122m+60m+40m= 222m

C) 0,400Km+6000cm
400m+60m= 460m
