Have you ever heard of the phrase "the tip of the iceberg"? Only a small part of the iceberg is exposed on the water, and most of it is hidden under the water. Suppose the volume of an iceberg is 1000m? The exposed volume is 100m? . The volume of icebergs exposed to the water accounts for (1)/(kloc-0/0) of the total volume, and the volume below the water accounts for (9)/( 10) of the total volume.

3. Fill in the appropriate score on the horizontal line below.

25cm= 1/4m 36dm? =9/25m? 600g = 3/5kg 750ml = 3/4L 0.28dm = 7/25dm 258cm? = 129/500dm?
