Answer:
<u><em>SMALLEST TO GREATEST</em></u>
102 mm --> 125 mm --> 10.4 cm --> 0.12 m.
Explanation:
Millimeters (mm) is smaller than centimeters (cm). Centimeters are smaller than meters (m).
And, since both 125 mm and 102 mm has the same units of measurement, 125>102.
<em>So, 102 goes in front of 125.</em>
And then the rest of the order is completed by comparing the units of measurement.
