1 m ___ 1 cm ___ 10 mm.

The correct answer is: >, =

• A meter can be divided into 100 equal parts, each of which measures one centimeter.
• In other words, 1 m = 100 cm or 100 cm = 1 m.
• Similarly, a centimeter can be divided into ten equal portions, each measuring one millimeter (abbreviated "mm"). In other words, 1 cm = 10 mm or 10 mm = 1 cm.
• How many millimetres will compose a metre if a metre is converted to millimetres?
• 1 m = 100 × 10 = 1000 mm
• Hence C is the right option.
