Write these lengths in order of size, starting with the smallest. 0.043 km 433cm 4340mm 4.3m
Ahat [919]

The order of length measurement starting with the smallest is 4.3 m, 433 cm, 4340 mm, and 0.043 km.

To compare the given measurements of length, they should have similar units. In this case, we can convert each length measurement to meter. The following conversion of different units to meter is listed below:

  • 1 km = 1000 m
  • 1 cm = 0.01 m or 100 cm = 1 m
  • 1 mm = 0.001 m or 1000 mm = 1 m

Conversion of units to m:

  • 0.043 km * (1000 m/km)= 43 m
  • 433 cm * (0.01 m/cm) = 4.33 m
  • 4340 mm * (0.001 m/mm)= 4.34 m
  • 4.3 m

Lengths in order of size starting with the smallest:

  1. 4..3 m
  2. 433 cm or 4.33 m
  3. 4340 mm or 4.34 m
  4. 0.043 km or 43 m

Explain how an estimate helps you place the decimal point when multiplying 3.9 × 5.3
Elza [17]
So you can round 3.9 to 4, and 5.3 to 5. so 4x5=20. there would then be 2 digits in front of the decimal point. (:
