Answer: 7/12 and 3/12

Step-by-step explanation: There are 12 biscuits, so let's take the digestive biscuits and the ginger biscuits.

There are 3 ginger biscuits out of all the 12 biscuits so 3/12 or 3 out of 12

Now let's do the digestive, there are 7 digestive out of all 12 biscuits, 7/12 or 7/12
