Find the missing number for each unit rate? 10/2 =? /1 and 16/4=? /1

The appropriate answer is 'the liquid state is more dense than the solid state'. This phenomenon explains why ice floats when it is frozen. When water freezes it expands by approximately 10 percent. It also becomes less dense. This explains why only 10 percent of an iceberg is above the ocean water and the remaining 90 percent is below the waves.
