Change can be described using multiplication or division. Division can be represented as multiplication by a fraction.
The sentence 'The __________ is ___ times the size of the __________' supports us to describe a comparison or change.
If units are different, we should convert so that they are the same - this supports us to calculate.
To find a missing factor, we can divide the product by the known factor.
