Sally has 2 cats and each cat eats a quarter of a tin of cat food each day.
Sally buys 9 tins of cat food.
For how many days will the cat food feed her 2 cats?
You must show your working.
I

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

tin  =  1 day

9 tins  =  x

cross-multiply

×  x  =  9

x  = 9

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

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

the probability is 0

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
