Divided only the first part by 2, leaving the second part (10) unsimplified
Applies an incorrect conversion factor when putting two quantities into the same unit
Wrote the ratio using the numbers as given (1:6) without converting to a common unit first
Simplifies a ratio directly without first converting its quantities to the same unit
Forgets to convert £4 to 400p before simplifying, and instead simplifies 4:60 directly (dividing by 4) to get 1:15.
