Answer 1

To find out how much of the cake each friend ate, you divide the total amount of cake eaten by the number of friends:

Total cake eaten = $\frac{3}{4}$ (in the problem it looks like a fraction) Number of friends = 9

So, each friend ate:

$$\text{Amount eaten by each friend}=\frac{\frac{3}{4}}{9}=\frac{3}{4}\times \frac{1}{9}=\frac{3}{36}=\frac{1}{12}$$

So, each friend ate $\frac{1}{12}$ of the cake.

Looking at the responses provided, the closest correct answer is:

112 (given the context it should refer to $\frac{1}{12}$).

However, if "112" is a typo and instead refers to $\frac{1}{12}$, that would be the most appropriate answer. If "112" is interpreted literally, the answer would be $\frac{1}{12}$.
