Order from smallest to largest:
cm, dm, mm, m
To order the given lengths from smallest to largest, we first convert all measurements to a common unit, such as centimeters:
Now, we can arrange the lengths in ascending order by their converted measurements:
Therefore, the correct order from smallest to largest is:
m
cm
mm
dm
m
cm
mm
dm
Convert to meters:
\( 40 \) cm
Choose the unit that makes calculations easiest! Centimeters work well here because most conversions avoid decimals. You could also use millimeters, but you'd get larger numbers.
Use the metric ladder! From largest to smallest: meter → decimeter → centimeter → millimeter. Each step down multiplies by 10, each step up divides by 10.
No problem! As long as you convert all measurements to the same unit consistently, you'll get the correct order. The relative sizes stay the same.
Be careful! Estimating works for obvious differences, but cm vs mm are very close (2 cm vs 3 cm). Always convert for accuracy.
Because meter = centimeters, so cm. Think of it as 1 hundredth of a meter equals 1 centimeter!
