Answer 1

Answer: (A), (C)

$3\frac{3}{4}$ rows

The pictorial representation of the pack of cookies is as follows:
David has eaten 15 cookies.
Each row contains 4 cookies.

$\therefore$ He has eaten $\frac{15}{4}$ rows of cookies.

Let's convert it into mixed fraction using long division.
Mixed fraction $=3\frac{3}{4}$
He has eaten $3\frac{3}{4}$ rows of cookies.
