Sally has 2 cats and each cat eats 1/4 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.

18 days

Step-by-step explanation:

Each cat eats 1/4 of the thin in a day, so between the two cats they eat:

 of the tin in one day.

if the two cats eat 1/2 of the tin in one day, this means that in 2 days they eat a whole tin of cat food.

we can represent this as follows

days     tins of cat food

 2                 1

and because she has 9 tins of cat food, and x represents the quantity of days:

days     tins of cat food

 2                 1

 x                 9

thus, we must multiply cross quantities from the table and divide by the remaining amount:

x = 2*9/1 = 18

the 9 tins of cat food will last 18 days

DE is congruent to BE , ED is congruent is EB and the last one is midpoint.
