Every day, the Monroe Pet Store uses 2 bags of dog food to feed the dogs. For how many
days will 1/3 of a bag of dog food last?

Answer 1

1/3 of a bag of dog food last will last for
`(1)/(6)`

Explanation:

Given:

Number of dog bag food used per day by Monroe Pet Store to feed the dog= 2

To find:

Number of days 1/3 of a bag of dog food last=?

Solution:

Let the number days for which the
`(1)/(3)` of bag of food lasts be x

For one day= 2 bags

for x days =
`(1)/(3)`

By cross multiplication method

`2x=(1)/(3)`

`x=((1)/(3))/(2)`

`x=(1)/(3)*(1)/(2)`

`x=(1)/(6)`
