Answer:
18 days
Step-by-step explanation:
Since each cat eats a quarter of a tin each day, this means the 2 cats eat half of a tin for each day
We can use proportion to solve this problem
Let x be the number of days the two cat will feed on 9 tins
[tex]\frac{1}{2}[/tex] tin = 1 day
9 tins = x
cross-multiply
[tex]\frac{1}{2}[/tex] × x = 9
[tex]\frac{1}{2}[/tex] x = 9
To get the value of x, we will multiply both-side of the equation by 2
2×[tex]\frac{1}{2}[/tex] x = 9 × 2
At the left-hand side of the equation 2 at the numerator will cancel-out 2 at the denominator
x = 18 days
Therefore it will take 18 days for the two cats to feed on 9 tins of cat food
