Step-by-step explanation:
To express the amount spent on advertising to its website as a ratio in its simplest form, we need to convert the given information into a ratio. The company spends 41 pence on its website for every pound spent on advertising.
We can simplify this ratio by dividing both parts by the greatest common divisor, which is 1.
The simplified ratio is 41:100.
Therefore, the correct answer is option a) 41:100.
