Answer 2

Question:

3. Convert these as directed:

Question:

(A) 256mm into cm and mm

Answer:

1cm = 10mm

1mm= 1/10cm

256mm= 256/10cm

256mm= 25.6cm or 25cm and 6mm.

Question:

(B) 204m into km

Answer:

1km = 1000m

1m = 1/1000km

204m = 204/1000km

204m = 0.204km.

Question:

(C) 725mm into cm

Answer:

1cm = 10mm

1mm = 1/10cm

725mm = 725/10cm

725mm = 72.5cm or 72cm and 5mm.

Question:

(D) 32km and 69m into km

Answer:

(Here we have to convert the measurement given in m to km and add it with the rest of the measurement.)

1km = 1000m

1m = 1/1000km

69m = 69/1000km

69m = 0.069km

(Now add the two of the given measurements.)

32km + 0.069km = 32.069km.
