Question

Sally has 2 cats and each cat eats a quarter of a tin of cat food each day.

Answer 1

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

$\frac{1}{2}$ tin  =  1 day

9 tins  =  x

cross-multiply

$\frac{1}{2}$ ×  x  =  9

$\frac{1}{2}$ x  = 9

To get the value of x, we will multiply both-side of the equation by 2

2×$\frac{1}{2}$ 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
