Solution

The correct option is A 6
Given,
All the cat food $= \frac{3}{4}$
Amount eaten per week $= \frac{1}{8}$

$∴$ Number of weeks $= \frac{A l l t h e c a t f o o d}{A m o u n t e a t e n p e r w e e k}$
$= \frac{\frac{3}{4}}{\frac{1}{8}}$
$= \frac{3}{4} \times 8$
$= 3 \times 2$
$= 6$
Thus, the food would last for 6 weeks.
